瓶坯模具使用性能的好壞，熱流道是關鍵。本廠設計的熱流道，吸收了國外的先進技術，結合國內客戶的需要，采用免剪澆口設計，熱流道噴咀單獨控溫。（單獨控制的優點以解決在生產過程中所產生的問題，例如底部發白、拉絲）。模具在全自動條件下生產，無需員工的頻繁操作，以減少工人的勞動力。模具的關鍵零件（型芯，型腔，口模）采用模具注腔、注芯選用瑞典原廠預熱處理**專用模具鋼（HRC45），保證了模具的使用壽命與瓶質量（正常使用200萬次免維修，**大**小壁厚差小于0.05mm）。并采用車削加工中心加工，保證零件的加工質量，實現互配。冷卻水道的合理布置，更使得模具有較高的生產效率，成型周期短至15秒（需配合冷機，適合的瓶坯設計及適合的注塑機）。完全自主研制開發的新型瓶坯模具結構,完全屏棄過去模具的大部分弊端,能夠達到模具高精度同心,高壽命,且能進行模具各零部件的標準化,大批量的生產。我們的模具保證管坯壁厚差小于0.05mm，重量誤差小于0.3g，一分鐘可出2-5模，壽命可達200萬模次，模具**大有48腔

      熱流道無澆口氣封瓶坯模具：●1.瓶胚采用電腦模擬拉伸測試設計,提高吹瓶的成品率. ●2.采用世界先進的二級雙錐度定位技術,每腔獨立自鎖,確保模具同心度（偏心在0.05-0.06mm以內）。. ●3.模具注腔、注芯選用瑞典原廠預熱處理**專用模具鋼制造。●4.螺紋口按國際標準制造，材料選用進口氮化鋼，硬度高，使用壽命長。●5.熱流道設計先進，加熱溫度均勻，可提高塑料制品質量。●6.免剪澆口，降低工人勞動強度。●7.工藝先進，加工精度高，各配件可互換，使用更方便。●8.常溫水冷卻實現高效率，全自動生產與進口模具相**。

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.
