Steel selection guide
P20 / 718H for general production and standard Class A; NAK80 for ultra-high polish; S136 for corrosive resins; H13 for abrasive fillers and high-wear areas. BeCu inserts where fast, localised cooling is critical.
Mould base & standards
LKM / HASCO standard base; plates in P20 / 1730 / 2312 as specified. Modular inserts designed for easy service and steel replacement without retooling the full mould base.

How to source car door trim moulds from China
A practical three-step guide for procurement teams evaluating and ordering automotive interior tooling from Chinese suppliers.
Research and evaluate suppliers
Start on platforms like Alibaba, Made-in-China, and Global Sources to build a long-list of automotive mould makers. Prioritise suppliers with verifiable years of experience in automotive interior tooling, ISO 9001 / IATF 16949 certification, and traceable customer references. Request sample parts from shortlisted suppliers — inspect material quality, precision, and surface finish. Ask about their DFM process, quality control protocol, and trial-shot procedure. A good supplier answers in detail without hesitation.
Negotiate and place your order
Come prepared to discuss unit pricing against market benchmarks, minimum order quantity (MOQ), lead time commitments, and payment terms — letter of credit, escrow, or trade insurance all offer financial protection. Get a detailed purchase agreement covering product specification, quality standards and tolerances, delivery and shipping terms, and warranty scope. Before shipment, conduct or commission quality checks: dimensional inspection, material composition testing, appearance and finish review, and any applicable function tests. Consider an independent third-party inspection service for unbiased verification. Weigh air freight (faster, higher cost) versus sea freight (economical for volume, longer transit) and engage reputable freight forwarders for customs clearance.
Import compliance and after-sales support
Know your country’s import duty and customs documentation requirements for automotive tooling — commercial invoice, packing list, bill of lading, certificate of origin, and any required safety or compliance certification. Confirm after-sales terms before ordering: how defects are handled, what warranty period applies, and how responsive the supplier’s engineering team is post-delivery. A reliable partner resolves issues proactively and supports process optimisation throughout the production run.

Car door trim mould FAQ
What vehicle segments and capacities do you support?
We design and manufacture injection moulds for front and rear door trims across passenger cars, SUVs, MPVs, and light commercial vehicles. Trim sizes cover compact to full-size segments with variants for base, mid, and premium interiors. We customise moulds to OEM drawings or co-develop based on your styling, NVH, and regulatory targets.
What is the expected mould lifetime and which steels do you recommend?
High-quality door trim moulds are engineered for 300,000 to 800,000 shots depending on steel grade, process stability, and maintenance. We commonly use P20/718H for general production, H13/S136 for high-gloss or abrasive-filler applications, and BeCu inserts for fast cooling at critical zones. Proper preventive maintenance and stable processing significantly extend service life.
What is the typical cycle time for door trim moulding?
Cycle time typically ranges from 35 to 70 seconds depending on part size, wall thickness, material, and surface class. Optimised cooling channels, conformal inserts, and balanced gating reduce cycle while maintaining dimensional stability. Large SUV trims expect 55–70 s; compact car trims often run 40–55 s.
Do you support in-mould decoration — IML, IMD, and graining?
Yes. We provide moulds ready for IMD/IML, in-mould graining/film, and laser-engraved texture per OEM standards. Precision locating features, anti-static label systems, and automated film feeding can be integrated. These technologies deliver durable surfaces, premium appearance, and lower post-processing cost.
What is the lead time for a custom car door trim mould?
Typical lead time is 60–75 days from design approval to shipment, covering DFM, mould design, CNC/EDM machining, heat treatment, polishing, assembly, and T0 trials. Fast-track deliveries in 45–55 days are available subject to complexity and a surcharge. Trial parts and full test reports are provided before dispatch.
Do you engineer for single-shot, 2K/3K, and overmoulding?
Yes. We engineer single-shot PP/ABS/PC-ABS trims, 2K/3K overmoulding for soft-touch TPE/TPO pads, and insert moulding for metal or clip features. Our team balances aesthetics, bond strength, and cycle time to meet your cost and performance targets. We also prepare moulds for post-assembly foaming or lamination.
Which materials are common for door trims, and can you advise on selection?
Typical materials include PP-TD (talc-filled), ABS/PC-ABS, TPO/TPE for soft-touch zones, and GF-modified resins for stiffness-critical areas. PP-TD is cost-effective with good dimensional stability; PC-ABS suits higher impact requirements and better surface class. We tailor gating, venting, and shrink management to your chosen resin and OEM specifications.
Do you offer multi-cavity or family moulds for door trims?
For large door trims, single-cavity moulds are standard due to size and press tonnage limits. We offer family moulds for left/right variants or sub-components such as armrests and map pockets to improve efficiency. Multi-cavity is feasible for smaller interior parts but requires higher clamp force and larger platens.
