How to make good quality injection mould?
A-Mould Design Stage
1. We meticulously analyze key factors such as feasibility, shrinkage, and molding temperature to ensure perfection in your plastic products.
2. Engaging in comprehensive communication with customers, we delve into every detail, including weight, style design, size appearance, injection molding stability, and the applicability of various plastics.
3. We select the ideal steel tailored to the plastic material, mold longevity, and specific customer requirements.
4. Benefit from our complimentary design and mold flow analysis services.
B-Mould Manufacturing Stage
1. Once the mold drawing is confirmed, our production process kicks off with precision and efficiency.
2. Our comprehensive process includes mold steel preparation, CNC rough machining, wire cutting, EDM machining, parts finishing, polishing, assembly, mold trials, and advanced treatments like electroplating and nitriding.
3. We rigorously control dimensions and self-inspect each mold part, ensuring they meet the precise specifications and tolerance ranges of the drawings.
C-Mould Testing
1. Our initial mold trial checks for normal production and accurate sizing of the product.
2. Post-polishing and surface treatments like sun-texturing, we reevaluate the mold and compare trial samples with the product design.
3. We provide customers with the final sample and a video of the mold trial for confirmation, ensuring satisfaction.
D-Mold Delivery
1. Before dispatch, we thoroughly verify the seamless operation of mold opening and closing, along with the integrity of the water cooling, hydraulic oil, and hot runner systems.
2. We ensure the cavity and core are pristine, free from iron filings and impurities.
3. We blow clean the waterway to prevent rust during extended sea transport.
4. The mold is protected with an anti-rust agent inside, exterior paint, and anti-rust oil on the ejector pin.
5. A nameplate detailing the mold's name, production year, information, weight, and size is affixed for easy identification.
6. We provide mold accessories free of charge for customer convenience and replacement.

Mould Maintenance Tips
1. Routine maintenance involves lubricating moving parts like thimbles, guide posts, and sleeves, cleaning the mold surface, and ensuring water pathways are clear.
2. Regular maintenance includes cleaning exhaust grooves, removing trapped air and black spots, and repairing damaged or worn parts.
3. For appearance maintenance, the mold's exterior is spray-painted to prevent rust. Both fixed and movable molds are coated with anti-rust oil and stored airtight to keep dust out of the cavity.
