Mould size: 550*450mm (advice to choose 250T injection molding machine)
Mould cavity: single
Mould steel: 718 forging steel, the original hardness is HRC30 degree
Mould steel treatment: at final arranged hardness treatment for the core and cavity plates to HRC35 degree
Gateway: hot runner
Cycle time: 45 sec
At final for the stool mould on normal, we will arrange by electric plate treatment, in order to product prefect surface stool.
We made not only normal stool mould, but also foldable stool mould, big stool mould, baby stool mould, 2 steps stool mould, etc.
The technology of plastic stool mould
1. Mould structure design
Professional designers provide you with reasonably designed mould to shorten cycle hours. Reducing unnecessary procedure improves efficiency.
2. Mould cooling system
According to the structural characteristics of the product and the appearance of the product, We design a reasonable form of the gate for mould, such as a large gate, hidden gate, fan gate, needle gate, pinpoint gate, etc., a reasonable channel of runner design make mold temperature balance in the shortest time to improve mould precision and productivity.
3. Accessory for mould
Slide, guide pin, guide sleeve, lifter blocks and so on are taken by wear-resistant standard parts, to ensure the mould life.
4. Deal with mould
Quenching the mould, heat treatment to improve the hardness, then Nitriding temperature is lower, the mold will no longer need to quench mold with high surface hardness and wear resistance more than HV850.
