-If this crate mould can work full automatic or not?
Yes, this crate mould can work full automatic by oil cylinders move.
-If this crate mould can designed by more cavities or not?
Yes, can be designed and make, at most can be designed 2 cavities we made;
-If this crate mould cycle time can be more short or not?
If client would like choose beryllium bronze for inserts will be much more faster cycle time.
-If this crate mould fill material even or not?
Yes, this crate mould we designed total 4 gates to fill material, all of them are big gates, fill material very fast and also if choose recycle material also no problem to product.
-At final how to do for this crate mould surface treatment?
On normal we will arrange electric-plate for the core and cavity bottom plates, arrange thur. Nitrogen for sliders for the sliders, but if client choose different steel then has different treatment way.

Technology
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
Service
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.
