Product Details
Custom injection molding services produce high-volume plastic and metal parts by injecting molten material into precision-engineered molds. This manufacturing process delivers complex geometries, tight tolerances (±0.05 mm), and excellent repeatability at scale. Ideal for automotive, medical, consumer goods, and industrial applications requiring 5,000+ annual units.
What are Custom Injection Molding Services?
Custom injection molding services involve designing and manufacturing molds, then using them to produce identical parts by injecting molten thermoplastic or metal injection molding (MIM) feedstock into a closed cavity. The material cools and solidifies, taking the exact shape of the mold. This process offers exceptional repeatability—millions of parts with consistent quality—at low per-unit costs after mold investment. Capabilities range from micro-molding (parts as small as 0.1g) to large components (up to 5kg), with cycle times typically 15-60 seconds per shot. Multi-cavity molds (up to 128 cavities) enable high-volume production exceeding 1 million parts monthly.
