SWY mould attaches great importance to the QC of injection mould under various making processes, including: 

Mould & product design inspection 

Designs made by us or offered by customers are always analyzed in-depth by checking the molding process feasibility, mould structure and movement feasibility of all the related plastic components etc. This helps to avoid mould modifications in the later stages and other unnecessary mould repair work which may be caused by a product design fault. We believe that if we spend more time during the product & mould designing stage we can fasten the mould making time.

Mould steel inspection

Plastic injection mould steels are bought from standard sellers and selected according to specific conditions and customer requirements. 

Suggestions here:  

*If your mould needed production quantity is high, suggested using H13 (common mould cavity/core, heat treatment HRC43-52), S136 (anti-corrosion and high mirror finish, heat treatment HRC43-52), 718S (high mirror finish, heat treatment HRC43-52), NAK80 (high mirror finish, pre-hardening HRC38-42), NAK55 (high mirror finish, heat treatment HRC43-52), 2316 (anti-corrosion and high mirror finish, heat treatment HRC43-52), 2738H (high mirror finish, pre-hardening HRC30-33), SKD61 (used for precision moulds, heat treatment HRC45-58)   

*If mould needed production quantity is not so high, suggested using 2311/P20H (common mould cavity/core, pre-hardening HRC28-33), 718H (with good polishing, pre-hardening HRC33-38)

Mould standard spare parts inspection

All spare parts, SWY mould buys from the regular brand. As for spare parts, we will protect all the drawings if customers need, and offer a quantity of spare parts on the quotation itself. For standard spare parts, you can ask us to help you buy and send to you and common spare parts also can purchase from your market.

Heat treatment inspection 

Some suggestions for the treatment of steel in the processing of plastic injection mould:

In the beginning, the structure must be designed first, and choose a material formula according to designed structure, to ensure mould base, mould core cavity, slider section can be used scientifically.

Mould steel used is recommended to be treated three times. Firstly it is quenching and tempering treatment; then it is vacuum treatment with a vacuum of 43-52 degrees; finally, ensure the temperature is tempered for 48 hours. It is very important to control the distance between mould steel in the furnace to ensure that each treatment is uniform. If treatment is not proper, uneven hardness will easily cause mould steel to rupture. 

Machining process inspection 

Every week we will provide a weekly report with pictures or videos so that customers can know the rate of progress clearly. All sizes and machining situation will be checked by our project manager through every machining phases if there is any fault can be corrected soon.

Mould trial inspection 

Our mould trials are conducted under the supervision of experienced technical personnel who strive to adjust the molding machine parameters and produce qualified samples. We also encourage our customers to visit the trials for their satisfaction.
