STEP/IGES/CAD input → DFM feedback in 3 days. Aluminum (prototype) or steel (production) molds.
Trimming, primer + topcoat (RAL/Pantone), insert molding, gasket grooves, threaded bushings.
100% dimensional inspection, CMM available, batch report attached per shipment.
MOQ: 50 pcs (aluminum) / 500 pcs (steel). First article 18–25 days. Batch 25–35 days FOB.
Full-body shell sets for robot dogs. Complex curves, zero sink marks, paint-ready.
Forearm covers, base housings, cable management channels. Lightweight & durable.
Chassis covers, sensor pods, bumper shells for autonomous guided vehicles.
Yes. As a ductile thermoset, PDCPD deforms and absorbs energy rather than cracking. Ideal for mobile robots that experience falls.
Leather grain, fine matte, high-gloss, soft-touch paint, EMI-shielding coating — all achievable via mold texture or post-processing.
Yes. Threaded inserts, boss structures, and mounting flanges can be molded in. Reduces secondary assembly steps.
~30 days including aluminum mold and first-article approval. CNC prototype available prior to mold commitment.
Yes. NDA available before STEP exchange. Your design files are never shared with third parties.
Up to 2 m in a single shot. For larger parts, we design split molds with seamless mating surfaces.
