We can use 2738 or 718 die steel, HRC 35-38, we can also use 2311 or P20, HRC 29-30, we can also use 2738, S136, die steel depends on your mold life and product quality requirements. For good cooling, we can add copper to the top of the core and the bottom of the cavity, which will shorten the cycle time. In addition, the cooling line will surround the barrel wall of the plastic injection mold. We use hot runner point gates for small injection barrel molds, hot runner direct gates for larger barrel molds, and variable hot runner direct gates for the largest injection barrel molds. Our company can also provide you with related injection molding machines and related auxiliary machines.
Mold maintenance is more important than mold maintenance. The more times the mold is repaired, the shorter the life is. The better the mold is maintained, the longer the service life will be. There are three main points in mold maintenance:
1. Daily maintenance of the mold: various moving parts such as thimble, row position, guide column, guide sleeve refueling, mold surface cleaning, water transporting the road, which is maintained every day when the mold is produced.
2. Regular maintenance: Regular maintenance, including daily maintenance, also requires the cleaning of the exhaust vents, trapping the black spots and exhausting, and repairing the damage and wear parts.
3. Appearance maintenance: paint on the outside of the mold base to avoid rust. When the mold is used, the fixed mold should be coated with anti-rust oil. The mold should be closed tightly when it is stored to prevent dust from entering the cavity.
