一.Collapsible pipe fitting mould:
leading technology enterprises of collapsible pipe fitting mould, and got patents.
Futures: the product out diameter is smaller than inner diameter, it enssure the product smoothly and fast eject after injection
Dimension: ¢20-¢400 …ect
Technical advantage:
1. Moderate hardness components , improve the mould life
2. The components to be standard.The high precision and consistency components can batch process and interchangable use.
4. The finished products eject from the mould smoothly.
二、Rotation Mould
To meet the needs of high standards for various pipe ,Jingzheng Design team through continuous efforts and practice, has researched and developed a various of big radian moulds, like 90degree, U-type,J-type,S-type …etc
Technical advantage:
1.Adopted rotation core-pulling and outside ejection way to ensure automatic ejection
2. Compact mould design, let the rotation core-pulling construction mould suit to smallest injection machine and reduce client’s investment cost.
3. Good lubrication and hardness to ensure the mould life.
三、Thread Mould:

With the Increasing usage of thread for the plastic parts, the demands for mould is keep increasing, it’s demand for more high quality, high precision, short cycle time . JINGZHENG never slack, research and develop various construction moulds including vertical core-pulling, horizontal core-pulling and core- pulling after open mould , it’s not only shorten the cycle time and increased the production ,but also the mould construction and mould production is very stable
Technical advantage:
1. Rotation is not scratched the thread , ensure the thread with higher precision
2. Keep a balance for Rotation device of material and hardness ,ensure the device life.
3. core-pulling after open mould, decreased the production cycle and increased the production efficiency.
