Y280-V6 一步式注塑拉伸吹塑机（6工位）

EBM | Extrusion Blow Molding

EBM starts with a hot hollow parison formed by an extruder. The mold closes around the parison, and compressed air expands the plastic into the mold cavity. This method is highly flexible for producing large containers, handled bottles, drums, and HDPE packaging where exact neck precision is less critical. Common materials include HDPE, LDPE, PP, and PVC.

The primary advantage of EBM is shape freedom. Parison extrusion can form handles, wide bodies, and offset shapes more easily than injection-based processes. However, parison sag under gravity can create uneven wall thickness, and the mold closing process often produces flash that requires trimming. For buyers, the main quality risks are inconsistent wall distribution around handles or shoulders and less precise neck thread definition.

IBM | Injection Blow Molding

IBM starts with an injection-molded preform where the neck, thread, and sealing area are formed with high dimensional precision before the bottle body is blown. The preform is transferred into a blow mold and inflated into its final shape. Because the neck geometry is established during injection before blowing, IBM produces exceptionally accurate thread definitions and closure sealing surfaces.

This precision matters most for small pharmaceutical bottles, eye-drop containers, cosmetic jars, and medical packaging where cap and pump fitment must be leak-free. IBM also produces consistent bottle weight and repeatable dimensions. However, IBM does not include a stretch rod, so the biaxial orientation benefits of the ISBM process are not achieved, making IBM less suitable for large or lightweight PET containers where strength and clarity at low wall thickness are priorities.

ISBM | Injection Stretch Blow Molding

ISBM is the process used in the Y280-V6. Like IBM, it starts with an injection-molded preform that establishes the neck geometry. But ISBM adds a stretch rod that extends the preform vertically before compressed air expands it outward. This biaxial orientation aligns the polymer molecules in two directions simultaneously, producing bottles with significantly improved clarity, top-load strength, gas barrier performance, and lightweight potential.

These properties are critical for PET water bottles, carbonated beverage packaging, edible oil containers, and clear cosmetic bottles where both performance and visual clarity matter. The single-stage injection stretch blow molding machine design of the Y280-V6 combines injection and blow molding in one continuous cycle without secondary preform reheating, achieving 15 to 25% energy savings compared to two-step systems while maintaining superior bottle quality and production speed.

Step 1: PET Resin Drying and Hopper Loading

PET resin for beverage bottle production must be dried to a moisture content below 50 ppm before processing to prevent hydrolytic degradation during melt injection. A dehumidifying dryer operating at 160 to 170 degrees Celsius for 4 to 6 hours is typically required. Dried PET pellets are loaded into the machine hopper, which feeds the injection screw. Undried PET produces bottles with reduced intrinsic viscosity, visible surface haziness, and reduced mechanical strength that can cause bottles to fail burst pressure or drop tests during quality control inspection.

Step 2: Preform Injection Molding

The dried PET resin is fed to the screw barrel, melted at temperatures typically between 270 and 285 degrees Celsius, and injected under precise pressure into the injection mold to form the beverage bottle preform. The preform shape, including the neck thread, sealing surface, and body wall thickness distribution, is determined at this stage. For carbonated beverage bottles, neck finish accuracy is especially critical because the crown or screw cap must seal reliably against the internal CO2 pressure of 2.0 to 4.5 bar. The preform is partially cooled to a stable but pliable temperature before transfer.

Step 3: Temperature Conditioning and Turntable Transfer

The servo-driven rotary turntable transfers the freshly injected preform from the injection station to the temperature conditioning zone. The integrated control box temperature system manages thermal equilibration across the preform body length to achieve a consistent temperature profile before stretching begins. For beverage bottles, the optimal preform temperature for biaxial ISBM stretching is typically 85 to 100 degrees Celsius, varying by bottle design and wall thickness target. Uneven preform temperature at this stage is the most common cause of shoulder thinning, base thickening, and pearl white opacity in the finished bottle.

Step 4: Biaxial Stretch Blow Molding

The conditioned preform enters the blow station where the mold closes around it and a stretch rod extends the preform vertically to the base of the blow mold. High-pressure air at 2.0 to 3.5 MPa is then introduced through the blow pin to expand the preform outward against the mold cavity walls simultaneously. This biaxial stretching step is what produces the superior strength and clarity characteristic of ISBM PET bottles. For carbonated beverage bottles, the resulting molecular orientation improves CO2 barrier performance, burst pressure resistance, and thermal stability during hot filling or pasteurization processes.

Step 5: Mold Cooling and Bottle Solidification

Following the blow molding stage, the bottle is held inside the closed mold while cooling water circulated through the mold channels removes heat from the container surface. Cooling time is a direct determinant of cycle time and dimensional stability. For beverage bottles where high clarity and low haze are commercial requirements, rapid and uniform cooling prevents crystallization that would make the PET appear white or translucent. The Y280-V6 cooling water circuit maintains temperature at 20 to 25 degrees Celsius through the machine oil cooler, providing stable cooling conditions across extended production runs.

Step 6: Ejection and Quality Inspection

冷却完成后，模具打开，行程为170毫米的取料机构将成品饮料瓶从吹瓶工位取出。取出的瓶子被送至检验和后续包装区域。饮料瓶的质量检验通常包括：目视检查瓶身表面缺陷和透明度；测量瓶颈尺寸以确保瓶盖贴合；称重以确保灌装量一致；以及根据客户质量计划定期进行爆破压力和跌落冲击测试。通过检验的瓶子无需任何二次修整或表面处理，即可直接进入灌装线、输送系统或包装工位。

Step 7: Downstream Packing and Storage

Finished beverage bottles from the Y280-V6 production line are typically collected on conveyors, counted into specified lot quantities, and packed into corrugated cartons or plastic bags for shipment to the filling plant. For high-volume operations, automatic bottle counting and bagging systems can be integrated downstream of the ISBM machine ejection station. Bottles should be stored in clean, dry conditions away from direct sunlight and chemical vapors that could affect PET surface quality before filling. Proper downstream handling protects the investment in bottle quality that the ISBM process provides throughout the entire production chain.

Maintenance and Care

1. Daily Lubrication and Mechanical Checks
At the start of each production shift, inspect all lubrication points on the clamping unit, turntable bearing, and ejection mechanism. Apply grease to specified points according to the maintenance schedule provided in the machine manual. Check that the turntable rotation is smooth and that no unusual vibration or noise is present during indexing. Verify that all air cylinder rod seals are intact and that there is no air leakage at cylinder connections. Addressing minor lubrication deficiencies early prevents accelerated wear on precision components and avoids unplanned downtime during production runs.

2. Hydraulic System Oil Management
300升液压油箱应每周检查油位、颜色和污染情况。新鲜的液压油通常呈浅琥珀色；颜色变深或浑浊则表明存在氧化、水污染或磨损密封件造成的颗粒污染。应按照制造商规定的周期彻底更换液压油，通常为每运行2000至3000小时更换一次。每次更换液压油时，应清洁或更换液压油滤清器。保持液压油清洁至关重要，因为YUKEN液压控制阀和高压部件的内部间隙很小，对颗粒污染非常敏感，会导致阀门卡滞、压力波动和部件加速磨损。

3. Cooling Water Circuit Maintenance
The cooling water circuit should be inspected monthly for scale buildup, biological growth, and flow rate consistency. The machine oil cooler must maintain water temperature between 20 and 25 degrees Celsius and pressure between 0.3 and 0.4 MPa to keep hydraulic oil viscosity within the operating range. The mold cooling circuit operates at 0.4 to 0.6 MPa and must be monitored for blockages that could cause uneven mold cooling and dimensional variation in bottles. Use treated water or a closed-loop cooling system with corrosion inhibitor to prevent scale and corrosion that would reduce heat transfer efficiency and restrict flow through mold cooling channels over time.

4. Screw and Barrel Cleaning
The injection screw and barrel should be purged and cleaned whenever changing between resin types or colors, and at scheduled intervals during extended production runs of the same material. For PET and PETG, purge with a commercial purging compound or a compatible transition resin to remove degraded material from the screw flights and barrel walls. Degraded PET deposits can cause black specks, yellow streaking, or molecular weight reduction in the finished container if not removed. The nano far-infrared heating ring system heats the barrel uniformly, but stagnant material in low-flow zones can still degrade if the screw is left stationary at temperature for extended periods without purging.

5. Mold Inspection and Cavity Care
Mold tooling should be inspected at regular intervals for wear on the cavity surface, parting line, venting channels, and neck ring components. Clean cavity surfaces with approved mold release agents and plastic-safe solvents to remove resin deposits and oxidation. Inspect water channel connections on the mold for leaks or blockages and verify that the cooling circuit is balanced across all cavities. Misaligned or worn parting surfaces can create flash on bottles, which affects container appearance and may indicate clamping force imbalance. Store molds in climate-controlled storage with protective coating on metal surfaces when not in production to prevent corrosion and humidity damage.

6. Servo Motor and Electrical System Checks
The Inovance or WEICHI servo motors driving the Y280-V6 clamping and injection systems should be inspected quarterly for bearing temperature, encoder signal quality, and cable condition. Check servo drive units in the electrical cabinet for adequate ventilation and absence of dust buildup that could cause overheating or signal interference. The Inovance or MiRLE PLC should have its battery backup status checked annually to ensure parameter memory is retained during power outages. Review the PLC fault log monthly to identify recurring alarms that may indicate developing mechanical or electrical issues before they cause a production stoppage. All electrical connections should be retorqued at commissioning and at annual service intervals to prevent high-resistance contacts from developing.

常问问题

Q: What is the difference between the Y280-V6 and a standard four-station injection stretch blow molding machine?
A: The Y280-V6 uses a six-station rotary turntable instead of the four-station design common in Japanese ISBM machines. This means the Y280-V6 can process six preforms simultaneously in a single rotation cycle, producing more bottles per cycle than a four-station machine running the same tooling configuration. In addition to higher output, the extra stations allow for longer temperature conditioning and cooling dwell times, which can improve bottle quality when running demanding materials or complex shapes.

Q: Can the Y280-V6 use existing ASB or Aoki injection stretch blow molding machine molds?
答：是的。Y280-V6 的设计兼容最初为日本 ASB 注塑拉伸吹塑机生产的模具，特别是 ASB-12M 和 ASB-70DPH 型模具。CMN 的产品系列还包括兼容 Aoki 100、Aoki 250 和 Aoki 500 型模具的型号。这种模具兼容性对于已投入模具资金并希望在不更换所有模具的情况下改用 CMN 设备的制造商来说，是一项重要的商业优势。请在购买前联系我们的销售团队，提供您现有模具的规格，以确认兼容性。

Q: Is a fully electric version of this one step injection stretch blow molding machine available?
A: Yes. CMN Transmission offers the Y280-V6 in a Fully Electric configuration that replaces all hydraulic drive systems with servo motors. The fully electric version produces no hydraulic oil, making it suitable for pharmaceutical manufacturing facilities that must comply with GMP standards and operate in clean-room-adjacent environments. The fully electric version also offers advantages in energy consumption, positioning repeatability, and quieter operation. It is available at a higher initial cost than the Standard or Servo hydraulic-assisted versions.

Q: What materials can the Y280-V6 PET injection stretch blow molding machine process?
答：Y280-V6 主要设计用于加工 PET 和 PETG，这两种材料是 ISBM 生产中最常用的。但是，通过选择合适的螺杆直径、调节料筒温度和进行干燥预处理，该机器也能加工 PP、PC、Tritan、PPSU、PCTG、ABS、PS 和 PLA 等材料。不同的材料需要不同的加工参数，CMN 的技术团队可以在交付前根据您的具体材料和瓶型设计，提供合适的配置建议。

Q: How much energy does the Y280-V6 single-stage injection stretch blow molding machine save compared to Japanese equivalents?
A: The Y280-V6 consumes 15% to 25% less energy than comparable Japanese, European, or American injection stretch blow molding machines running similar bottle designs and output volumes. This saving comes from three sources: the servo pump systems which only generate pressure on demand rather than running continuously at full flow, the nano far-infrared screw heating rings which reduce heat loss compared to conventional resistance heating, and the single-stage ISBM process which eliminates the secondary preform reheating step required by two-stage blow molding systems. Actual savings vary by bottle design, cycle time, and local utility rates.

Q: What bottle sizes and volumes can the Y280-V6 ISBM machine produce?
A: The Y280-V6 accommodates bottles from 20 ml to 2,500 ml in volume, with bottle diameters from 20 mm to 120 mm and bottle heights up to 210 mm. The machine can run from 1 to 10 cavities per cycle depending on bottle size, with neck diameters from 12 mm up to 85 mm. The product dimensions table provides the maximum bottle specifications at each cavity count. Custom bottle dimensions outside the standard table can be discussed with the CMN engineering team, who will assess mold feasibility and machine stroke compatibility before confirming the order.

Q: What is the difference between a one step ISBM machine and a two-step PET blow molding machine?
A: In a one step ISBM machine like the Y280-V6, the plastic resin is injected into a preform and immediately transferred to the stretch blow molding station within the same machine, retaining the heat from the injection phase. No separate preform reheating equipment is needed. In a two-step system, preforms are injection molded separately, stored and cooled completely, then reheated in a second machine before blow molding. The one-step process uses less energy because it avoids the preform reheating cycle, has a smaller footprint because only one machine is required, and produces bottles directly from resin pellets. The two-step system offers greater flexibility for high-volume commodity PET bottle production where preforms can be produced and stored separately for flexible output scheduling.

Q: How long does installation and commissioning of the Y280-V6 take?
答：Y280-V6 的标准安装和调试通常需要 3 至 5 天，CMN 技术团队将在现场进行操作。该过程包括机器定位和调平、电气和气动连接、冷却水回路调试、液压系统注水和压力设定、模具安装和校准，以及使用买方提供的材料和模具进行初始生产试生产。在调试期间，还会同步进行操作人员培训，内容涵盖机器设置、参数调整、安全规程和基本维护。CMN 安装工程师的现场访问安排在机器交付时进行协调，具体取决于买方的准备情况以及现场所有公用设施和模具的可用性。

Q: What compressed air supply does the Y280-V6 injection blow molding machine require?
A: The Y280-V6 requires a compressed air supply capable of delivering blowing air at 2.0 to 3.5 MPa (20 to 35 bar). A high-pressure compressor is required to achieve the upper end of this range for certain bottle designs or materials. The volume of air consumed per cycle depends on the bottle cavity volume and number of cavities, with larger or more numerous bottles requiring more air per cycle. Buyers should calculate the required compressor capacity based on their expected production speed and bottle volume before installation. An undersized compressed air supply is one of the most common causes of startup delays on new ISBM machine installations.

问：Y280-V6 能否生产用于医药和食品接触应用的不含 BPA 的瓶子？
答：是的。Y280-V6 可加工不含双酚A (BPA) 的材料，包括 PET、PETG、PP、Tritan、PPSU 和 PCTG，所有这些材料均符合主要的国际食品接触和药品包装法规，包括 FDA、欧盟 10/2011 及同等标准。对于 GMP 要求完全消除液压油污染风险的药品应用，建议使用 Y280-V6 的全电动伺服配置。需要特定材料合规性文件或食品接触安全声明的买家，应在购买时向 CMN 和树脂供应商索取相关证书。

用户评价

金载元，韩国药品包装公司
“大约十四个月前，我们在首尔的药品包装厂安装了Y280-V6注塑机，说实话，这是我们做过的最明智的设备决策之一。我们使用六腔模具生产50毫升PET口服液瓶，瓶颈尺寸的一致性非常出色。自从从日本ISBM的机器换用Y280-V6后，我们密封面的质量控制不合格率从每千瓶约1.2%降至0.25%以下。能源成本的下降幅度也超出了我们的预期——我们的工厂工程师计算出，每生产一千瓶，电费降低了约22%。CMN的安装团队在调试期间花了整整四天时间与我们一起工作，非常细致周到。”

Rajesh Mehta，化妆品包装，印度
“我在孟买经营一条化妆品包装生产线，去年我们把一台老旧的日本单步成型机换成了Y280-V6。表面质量的提升立竿见影。之前我们的客户一直抱怨我们150毫升护肤品瓶子上的分模线痕迹很淡，换用CMN模具后，这个问题彻底解决了。这台机器对Tritan和PETG材料的加工非常稳定。生产周期更短，伺服系统的响应速度也明显更快。我之前还担心中国厂商的售后服务，但他们的响应速度非常快。我发给WhatsApp的消息通常几个小时内就能收到回复。”

艾哈迈德·哈桑，饮料包装，埃及
“我们为位于开罗的PET水瓶生产线订购了两台Y280-V6设备。从订单确认到交货大约需要10周，这在可接受的范围内。机器到货时状态良好，包装也符合出口标准。我们现有的日本ASB模具无需任何改动即可直接使用，这为我们节省了大量新模具费用。每班产量高于我们之前使用的四工位日本机器。如果人机界面支持阿拉伯语就更好了，但目前的英文界面对我们的操作员来说也足够用了。总体而言，生产成本降低了，产品质量也保持稳定。”

费尔南达·科斯塔，婴儿包装，巴西
“我们位于圣保罗的公司使用Tritan材料生产婴儿奶瓶，供应巴西零售市场。我们选择Y280-V6奶瓶机，正是因为它具备全电动配置选项，符合我们的G​​MP要求。该奶瓶机已运行约8个月，用于生产120毫升六腔婴儿奶瓶。各腔体之间的尺寸一致性非常好——瓶颈直径误差在0.15毫米以内，完全符合我们的公差要求。唯一不足之处是，备件文档的葡萄牙语版本可以更详细一些，但CMN公司提供了主要维护操作的视频教程，这对我们的技术人员很有帮助。生产效率一直很稳定。”

Budi Santoso，包装设备，印度尼西亚
“我在雅加达从事吹塑设备行业超过十五年，Y280-V6 的性能确实可以与日本同类产品媲美，而且价格更低。我们为一位客户购买了一台，用于生产 PP 和 PETG 材质的洗手液瓶，效果非常出色。瓶重一致性极佳，误差在正负 0.3 克以内，客户对此非常满意。我们实际测量的能耗数据显示，与之前用于生产相同瓶型的日本机器相比，Y280-V6 的能耗降低了约 20%。CMN 公司顺利完成了运输和报关手续。我一定会向其他客户推荐他们。”

穆罕默德·哈立德，饮料和食品包装，巴基斯坦
“我们在拉合尔生产PET果汁瓶和食用油瓶，在选择CMN之前，我们评估了三家不同的注塑拉伸吹塑机制造商。价格很有竞争力，但真正促使我们做出决定的是模具与我们现有ASB模具的兼容性。我们已经有六套模具，不想投资购买全新的模具。设备转移过程非常顺利，从投产第一天起，瓶子的质量就一直很稳定。我们的物流协调员提到，CMN提供的运输单据非常齐全，这使得清关速度比预期更快。备件供应也很充足——我们更换过两次小型液压阀，两个零件都在三周内到货。”

阮氏兰，化妆品包装，越南
“我们在胡志明市的工厂生产出口市场的化妆品瓶，Y280-V6注塑机已经运行了大约11个月。我们主要用它来生产200毫升和300毫升的PETG乳液瓶和精华液瓶，通常每次生产4到6个模腔。瓶子的表面质量非常好——自从我们换用这台机器以来，负责验货的欧洲买家没有提出任何表面质量方面的投诉。注塑过程中伺服系统的响应速度明显比我们之前的液压注塑机快。更换瓶型时的设置时间大约为40分钟，这对于我们的生产计划来说是可以接受的。在最初的三个月里，CMN的技术人员两次到我们工厂进行工艺参数的微调。这种程度的支持远远超出了我的预期。”

Thabo Ndlovu，饮料包装，南非
“我们在约翰内斯堡经营一家PET瓶生产厂，为整个南部非洲的饮料品牌供货。多年来我们一直采购日本设备，而Y280-V6是我们首次从中国ISBM设备制造商那里采购。我们的维护团队大概花了两个月的时间才完全适应，主要是因为他们习惯了日本设备的布局。就性能而言，机器运行可靠。十二个月以来，我们没有发生过任何重大故障——只有常规的计划维护。瓶子的透明度和爆破强度测试结果均符合我们的规格。我主要想提醒其他买家的是，要预留足够的压缩空气容量，因为Y280-V6的耗气量比老式低压设备要大。”

卡洛斯·拉米雷斯，合同包装，墨西哥
“我们是一家位于墨西哥城的合同包装制造商，18个月前将Y280-V6生产线引入到我们的产品线中。我们为多家客户生产250毫升至1000毫升的PET和PP材质的沐浴露、洗发水和洗手液瓶。六工位设计是我们选择它而不是竞争对手的四工位机器的主要原因，因为我们的客户期望快速交货。在我们实际的生产条件下，机器的生产速度非常出色。PLC配方存储功能对于管理不同客户的多种瓶型设计非常实用。给其他买家一个实用建议——在安装之前，请确保您当地的压缩空气供应能够满足3.5兆帕的吹气压力。我们最初就遇到了这个问题，导致启动时间延迟了大约一周。”
