热流道瓶坯模具 （注塑模具）热流道管坯模具 preform mould

瓶坯模具使用性能的好坏，热流道是关键。本厂设计的热流道，吸收了国外的先进技术，结合国内客户的需要，采用免剪浇口设计，热流道喷咀单独控温。（单独控制的优点以解决在生产过程中所产生的问题，例如底部发白、拉丝）。模具在全自动条件下生产，无需员工的频繁操作，以减少工人的劳动力。模具的关键零件（型芯，型腔，口模）采用模具注腔、注芯选用瑞典原厂预热处理**专用模具钢（HRC45），保证了模具的使用寿命与瓶质量（正常使用200万次免维修，**最小壁厚差小于0.05mm）。并采用车削加工中心加工，保证零件的加工质量，实现互配。冷却水道的合理布置，更使得模具有较高的生产效率，成型周期短至15秒（需配合冷机，适合的瓶坯设计及适合的注塑机）。完全自主研制开发的新型瓶坯模具结构,完全屏弃过去模具的大部分弊端,能够达到模具高精度同心,高寿命,且能进行模具各零部件的标准化,大批量的生产。我们的模具保证管坯壁厚差小于0.05mm，重量误差小于0.3g，一分钟可出2-5模，寿命可达200万模次，模具**有48腔

      热流道无浇口气封瓶坯模具：●1.瓶胚采用电脑模拟拉伸测试设计,提高吹瓶的成品率. ●2.采用世界先进的二级双锥度定位技术,每腔独立自锁,确保模具同心度（偏心在0.05-0.06mm以内）。. ●3.模具注腔、注芯选用瑞典原厂预热处理**专用模具钢制造。●4.螺纹口按国际标准制造，材料选用进口氮化钢，硬度高，使用寿命长。●5.热流道设计先进，加热温度均匀，可提高塑料制品质量。●6.免剪浇口，降低工人劳动强度。●7.工艺先进，加工精度高，各配件可互换，使用更方便。●8.常温水冷却实现高效率，全自动生产与进口模具相**。

Hengxin mould, specialized in manufacturing  PET Preform Moulds@(PET Preform Molds@) injection molding system, consists of  technologists with rich experience, and senior engineers with master's  degree and professional in 3D. We invite many technical committee members and senior professors in mould line are as the technical consultants for our company. Various kinds of processing equipment and detection measurement instrument are imported, as well as special drawing soft is applied in designing performs, samples and manufacturing testing mold. We supply special technology training and other good after-sales service.

A. Capacity of Research and Development
Hengxin mouldhas a powerful team for research and development, which is capable of manufacturing the perform molds with one cavity to ninety-six cavities including the injection system. At the same time we can manufacture perform molds especially according to customers' injection molding machines. We also design cold parts, hot runners and other main exchangeable components to fix on the imported perform molds.

B. Mould Features:
1. Features of the perform mold. No cutting of valve gate is employed to reduce the labor cost.
2.  Advanced hot runner system assures lower level of AA value.
3.  Reasonable- designed cold water channels increase cooling effect and shorten the cycle time.

C. Material
1. The main components of perform molds are made of S136 material (Swe**SSAB).
2. The mold base is made of imported P20.  plate method avoids corrosion efficaciously and assures long life service of the perform molds.
3. German Vacuum stove is imported for heat treatment of the components, which assures the hardness of components HRC45-HRC48.

D. Advanced Processing Equipment
Many machine tools are imported from America and Japan, such as Machine center, CNC lathers, EDM and so on. All of these increases processing precision, good interchangeability and low eccentricity≤0.10mm (perform length≤100).

E. Electric Heating Components
1. German Hotset heating components.
2. German intelligent temperature controller (PID continuous power controlling).
3. Offering temperature controller and voltage controller according to customers' requirement
F. Perfect Inspection Method.
Inspection tools include projector, hardness tester, stress tester, eccentric tester, electric balance and other inspection tools.
The screw neck is made and inspected strictly by the standard of Coca cola and the screw neck has been up to the standard of Coca cola.

G. After-Sales Service
 Technologists professional in after-sales line and excellent credit assures stable operation of the machines.
