Jasonmould Industrial Company Limited Specializes In Injection Molding For Different Applications The price of molds differs from their own standards. The society of plastic industry(SPI), a professional mold research association in America, divided molds into 5 standards, which have different manufacturing requirements. All of these molds are only suitable for the injection molding machine with 400 tons or less. In the following paper, we will introduce you these 5 kinds of molds:
Class 101 molds:
It rated for 1,000,000 times or more cycles, typically using in mass-up production, with the best raw material, so that the price is expensive. The mold design requirements:
1.
Itis necessary to have detailed information of mold design.
2.
Solidityof the mold base must at least reaches the level of 280
3.
Solidity standard of the mold surface(including cavities and cores) must be withinthe range of 450 Other accessories such as slider, lifter, coping should be made of hard tool steel.
4.
Ejector machine must have guiding elements.
5.
Slidersmust be equipped with wear plates.
6.
Temperature controller should be installed in cavities and cores,sliders and wherever if possible.
7.
For the service life of mold, the erosion of cooling water pipelinewill decrease the quality of products so that injection molding manufacturing cycle will be increased. Therefore it is suggested that the embedded parts of cooling water pipeline should be dealt with erosion resistant treatment..
8.
All kind of this moldshould be equipped with parting line locks
Class 102 molds:
Its cycle can reaches no more than 1,000,000 times for mass-up production, and its requirements as blow:
