How to make good quality bottle pet preform injection mould?
A: Mould Design
Good pet preform mould design is the first step,PRC mould has 3 designers with more than 15 years experience.
1:We will analyze the feasibility,shrinkage and molding temperature of plastic products.
2 :We will communicate with customers,including details such as weight,style design,size and appearance,stability and wear resistance of plastic products.
3:Design and mold flow analysis are provided free of charge.
B: Mould Metal Material
Choose different steel according to plastic product material,mould life and customers requirements.
We all buy mould raw material from large metal companies.
We personally test the hardness of the mould steel.
There are strict inspection procedures for the hardness of mould steel,and mould life is 1000000 to 3 million shots.
C: Mould Machine Tooling
After the pet preform mould drawing is confirmed,start production.
Including mold steel preparation, cnc rough machining, deep hole drilling, EDM,drilling machine,high-speed milling,finishing,polishing assembly,mold trial,electroplating,nitriding,etc.
Precisely control the size,and conduct self-inspection for each mould part according to the requirements of drawing size and tolerance limit control.
D : Mould Testing
The first time test we do on the mold is to check that it moves smoothly and correctly.
After the pet preform mold is polished,we will test pet preform mould again,compare the test samples with the original design.
Then send the final samples and pet preform mold testing video to customers for confirmation.
