Frequently Asked Questions

What is the plastic injection molding process?

Injection molding melts plastic pellets, injects the molten material into a mold cavity under high pressure, cools it until solid, then ejects the finished part. The process is automated, repeatable, and ideal for high-volume production.

What materials can be used in injection molding?

Common materials include PP, HDPE, LDPE, ABS, PC, PA (nylon), PMMA, POM, and TPE. Material selection depends on application requirements: strength, temperature resistance, food contact, ESD properties, or chemical resistance.

How much does injection molding cost?

Costs vary based on mold complexity ($5,000-$50,000+), material type, part size, and production volume. For high volumes (>10,000 units), per-unit cost drops significantly. LSY Plastic offers free quotes for custom projects.

How long does an injection mold last?

Quality steel molds last 500,000-1,000,000+ cycles. Aluminum molds last 10,000-100,000 cycles. Mold lifespan depends on material abrasiveness, maintenance, and operating conditions. Regular maintenance extends mold life by 30-50%.

What injection molding machines does LSY Plastic use?

LSY Plastic uses Japanese-imported molding machines from JSW, Mitsubishi Heavy Industries, and Nippon Steel, with clamping forces from 180T to 2500T, covering everything from small precision parts to large industrial products.
