Auto lamp moulds from Taizhou Huangyan Xiongxing Plastic Mould Co., Ltd. are precision injection tools engineered for producing polycarbonate and PMMA automotive lighting housings. The tooling supports high-pressure injection cycles with thermal resistance suited to lamp-grade polymer processing. Located in Taizhou, Zhejiang, the supplier operates from the North Industrial Zone on Jingsi Road, a region recognised for China's dense concentration of plastic mould manufacturing capability. The moulds accommodate variable lamp geometries including headlamp clusters, tail light assemblies, and indicator housings.
The mould cavities are typically machined from pre-hardened tool steels such as P20 or 718H, with core inserts often using beryllium copper for improved thermal conductivity. Hardened to HRC 28-34 for P20, these steels offer a balance of machinability and wear resistance for production runs exceeding 500,000 shots. Cooling channel design follows conformal or drilled configurations depending on part complexity, with typical channel diameters of 8-12 mm. Venting systems are critical for optical clarity in lamp lenses, typically achieved through parting-line vents of 0.02-0.05 mm and ejector pin placements that avoid visible surface marking.
Buyers are typically tier-one automotive lighting suppliers, aftermarket parts manufacturers, and injection moulding contractors serving OEM supply chains. Applications span projector headlamps, LED tail light modules, fog lamp bezels, and daytime running light housings. The moulds interface with standard injection machines from 280-tonne to 800-tonne clamping force depending on lamp size. Trade terms referenced include FOB and CIF, with payment by L/C or T/T, though specific MOQ and lead time should be confirmed directly with Taizhou Huangyan Xiongxing.
| Mould base steel | P20 or 718H pre-hardened steel (typical for automotive optical moulds) |
| Cavity/core steel hardness | HRC 28-34 (P20), HRC 33-38 (718H) - standard grades |
| Thermal conductivity insert material | Beryllium copper alloy (typical for high-heat-flux lamp core inserts) |
| Cooling channel diameter | 8-12 mm (standard range for medium-to-large automotive moulds) |
| Parting-line vent clearance | 0.02-0.05 mm (typical for optical-grade lens venting) |
| Compatible clamping force | 280-800 tonnes (standard injection machine range for lamp housings) |
| Shot life expectancy | 500,000+ shots (typical for properly maintained P20 lamp moulds) |
| Resin compatibility | Polycarbonate, PMMA, PC/ABS blends (standard automotive lamp polymers) |
| Surface finish requirement | SPI-A2 to A3 or equivalent (typical for visible lamp lens surfaces) |
| Gate type | Hot runner or three-plate cold runner (standard configurations for lamp moulds) |
Taizhou Huangyan Xiongxing Plastic Mould Co., Ltd. is located at Jingsi Road in the North Industrial Zone of Taizhou, Zhejiang Province, postal code 318020. Taizhou's Huangyan district has been a centre for plastic mould fabrication since the 1980s, with hundreds of specialist firms operating in close geographic proximity. The supplier is classified as an imported-tier listing with a harbour trust tier, indicating basic platform registration without additional verification signals. The response rate shows 0.00 percent with zero average response hours, which means buyers should not expect rapid quotation turnaround.
The company's profile does not state founding year, employee count, annual revenue, specific machinery inventory, or named automotive OEM clients. No ISO 9001, IATF 16949, or mould-specific certifications are confirmed in the source data. The supplier address places it within Taizhou's established mould-making district, suggesting access to local steel suppliers, heat treatment services, and CNC machining subcontractors. Buyers should request factory audit documentation, mould trial video evidence, and reference projects with comparable lamp part complexity before committing to tooling orders.

Before ordering, verify that Taizhou Huangyan Xiongxing can provide steel mill certificates for the actual P20 or 718H material used, not just material purchase receipts. Request CMM dimensional reports for a recently delivered lamp mould of comparable size and complexity, with particular attention to parting-line shut-off accuracy below 0.03 mm. Ask for video documentation of a mould trial running at quoted cycle time, showing ejection without part deformation. Confirm that the supplier holds liability insurance covering mould repair or replacement if premature failure occurs below quoted shot life.
Logistics from Taizhou Zhejiang typically route through Ningbo or Shanghai port for ocean freight. Confirm whether quoted Incoterms are FOB Ningbo, FOB Shanghai, or another port, and clarify who arranges inland trucking from factory to port. Payment terms mentioned include L/C and T/T, though the deposit percentage, milestone payment structure, and balance timing against shipment or acceptance should be negotiated explicitly. Ask for a detailed production schedule with design review, steel ordering, rough machining, heat treatment, finish machining, fitting, and trial milestones, as lead time is not stated in the source data and must be confirmed directly.
Quality verification should include on-site or third-party inspection before final payment release. Specify that mould acceptance criteria include dimensional inspection by CMM against 3D CAD, pressure testing of cooling circuits at 1.5x working pressure, and a minimum 100-shot trial with documented process parameters. Request that the supplier provides spare ejector pins, springs, and cooling seals in a maintenance kit. For optical lamp moulds, arrange for independent surface finish measurement by portable profilometer on delivered cavity inserts, verifying Ra 0.10-0.20 μm on critical lens surfaces. Documentation should include heat treatment certificates, steel composition reports, and a mould manual with assembly drawings and maintenance schedule.
