Injection Molded Parts in China

Prototype aluminum molds take 3_4 weeks. Production steel molds require 6_10 weeks. Part production adds 1_3 weeks after mold approval. Rush options available at select injection molded parts manufacturers.

From prototype runs of 50_500 pieces using soft tooling to high-volume production of 100,000+ units with steel molds. Specify your volume when submitting an RFQ.

Yes. Many verified manufacturers provide Design for Manufacturability feedback covering wall thickness, draft angles, gate placement, and undercuts before committing to tooling - reducing risk and rework on injection molded products.

Haizol offers three NDA levels: no NDA, a platform-standard digital NDA, or your own uploaded NDA. Suppliers must sign before accessing your 3D files. All communication and file access is logged for traceability.

Injection molded parts include housings, clips, caps, brackets, enclosures, gears, handles, connectors, medical components, consumer-product parts, and automotive plastic parts. Haizol profiles pair those product examples with resin experience, press range, tooling support, secondary processes, and QC documentation for similar components.

For custom injection molded parts, companies can use Haizol to upload the design file and describe resin, color, finish, tolerances, inserts, secondary operations, annual volume, and tooling status in special requirements. Those details help Chinese molding factories quote both part cost and production setup.

Injection molded part cost depends on tooling, resin grade, part weight, cycle time, cavity count, finish, tolerances, inserts, secondary operations, and production volume. Haizol's 2026 injection molding report explains why tooling amortisation, rather than a fixed MOQ, usually sets the practical quantity floor.

Typical injection mold components include cavities, cores, runner systems, gates, ejector pins, cooling channels, slides, lifters, and inserts. For requests through Haizol, naming these details matters when the part has undercuts, tight cosmetic surfaces, insert molding, or complex ejection requirements.

Choose an injection molded parts manufacturer by checking resin history, tooling support, press range, sample approval process, cosmetic standards, and quality-control records. Haizol factory profiles help companies verify molded-part examples, materials and finishing, production equipment, QC equipment, certifications, and Reviews & Ratings before contacting a factory.
