Custom rubber parts pricing depends on five drivers: material grade (Neoprene vs Viton can differ 3-5× per kg), cavity count and tooling complexity (single-cavity vs 32-cavity differ 20-40× in tooling), annual volume tier, tolerance class, and certification requirement. We do not publish a flat price list because doing so misleads buyers — your part with your specification needs a custom quote built around your actual production economics. Request a quotation through the form above and you will receive a complete-system breakdown within 24 hours, including tooling, sample, and shipping estimate.

From a confirmed PO and approved drawing: samples in 7-14 days using existing compound, prototype with PPAP-style validation in 3-4 weeks, tooling fabrication 4-6 weeks, and first mass production lot 4-8 weeks after tooling approval. Ongoing production releases run 3-5 weeks from each subsequent PO. Air freight from Guangzhou or Shenzhen typically adds 5-7 days; ocean freight 25-35 days to most U.S. and European ports.

Material selection follows three questions: what temperature range will the part see in service, what fluids will it contact, and what mechanical loading does it carry. EPDM excels outdoors but fails in oil. Nitril excels in fuel but degrades under UV. Viton handles high temperature and aggressive chemicals at premium cost. Silikon serves food and medical at moderate cost. Our engineering team supports the selection conversation before quoting, and the Materials and Tolerance Selection Guide PDF available above includes durometer matching, temperature compatibility, and ASTM D2000 line call-out worked examples.

Yes. Engelhardt holds active IATF 16949 certification audited and renewed annually by an independent certification body, in addition to ISO 9001. IATF 16949 extends the ISO 9001 quality management framework with automotive-specific requirements around defect prevention, error proofing, customer-specific requirements, control plan governance, and warranty management. Per certification authority DNV, IATF 16949 is the automotive equivalent ticket-to-trade and extends down to third-tier automotive suppliers, design centers, and corporate headquarters. We support full PPAP submissions including PSW, control plans, process flow diagrams, dimensional layouts, material certifications, performance test reports, and capability studies — the level of documentation an automotive Tier-1 OEM expects from a qualified rubber molding supplier. Customer audits at our Zhongshan facility are welcome and typically scheduled within two weeks of the request.

Yes to all three. Samples ship in 7-14 days on existing compounds. Small-batch MOQ is typically 500-1,000 pieces for catalog items. Mass production scales from 10,000 to several million pieces per year, with custom-tool MOQ negotiable based on amortization.

Spritzgießen heats and plasticizes the elastomer before injecting it into a closed mold cavity under high pressure — fastest cycle, tightest tolerance, highest tooling cost, best for high-volume complex parts. Formpressen places a measured preform into an open heated mold that closes under pressure — lowest tooling cost, longest cycle, moderate tolerance, best for large or thick parts at low-to-medium volume. Transferformen uses a plunger to push rubber through sprues into closed cavities — middle ground, particularly strong for insert molding and rubber-to-metal bonding. The right choice depends on geometry, volume, tolerance, and lifecycle cost.

Yes. The broader Engelhardt-Meitu operation runs 400 plastic injection machines (largest 2,000-ton presses, 100 tons/day plastic throughput) and a 1,000-square-meter automated hardware stamping line producing 30 million-plus pieces annually. The Integriertes Gummi-Kunststoff-Hardware-Montagemodell means an OEM with a multi-material sub-assembly can source the rubber gasket, plastic housing, metal insert, and final sub-assembly from a single supplier under one quality system and one PO.
