-How many gate points needed for this type of lunch box mould?
We will designed different depend on different thickness, if normal thickness 1 gate is enough, if thin thickness we need make 2 gates.
-How about the lock thin area work?
We are sure not easy broken, and lock can be doff easy by angle-lifter.
-How about final food box mould cavity surface treatment?
On normal choose texture, but also can be polish.

Mold quotationmost reasonable as rich experience
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 gate for mould, such as a large gate, hidden gate, fan gate, needle gate, pin point 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 mold, 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
1) We can repair the mould in one year for some free and provide technology. .
2) Gurantee period is 12months starting from the date of moulds accept in the Buyer’s factory.
3) If the moulds happen the big problem, The moulds cannot repaired, the Buyer cannot solve the problems,eg, mould crack, product can’t moulding…any big problem(except the human error) due to the mould life can’t reach to guranteed shots.the Seller and Buyer's negotiate to slove the problem, the buyer can send it back to the factory to repair or If serious, the Seller have resposiblity to make new mould for the Buyer.T Type fitting mold factory
