Custom Silicone Rubber Parts Compression Molded 70 Shore A for Auto Electronics

Custom Silicone Rubber Parts

Our custom silicone rubber parts are compression molded and injection molded from virgin silicone compound, with hardness from 30 to 80 Shore A. They are engineered for tight-tolerance sealing, vibration damping, insulation and protection in automotive, medical, household appliance and electronics assemblies. Both OEM drawings and reverse-engineered samples are accepted, and free 3D mold flow simulation is provided before tooling.

Application Scenarios

• Automotive: sealing rings, grommets, dust boots, cable sleeves and vibration mounts for engine compartments and EV battery packs.
• Medical & Laboratory: valves, diaphragms, stoppers and tubing connectors, steam sterilizable at 134 °C.
• Household Appliances: seals and bumpers for blenders, coffee machines, kettles and storage containers, odorless and non-yellowing.
• Electronics & Industrial: waterproof keypads, gaskets, thermal pads and connector boots rated IP67 to IP68.
• Machinery: oil-resistant EPDM and FKM alternatives available for hydraulic and pneumatic sealing.

FAQ

Q1: What is your minimum order quantity?
A: 500 pieces per model for stock sizes, and 2,000 pieces for new custom molds.

Q2: How long does a new mold take?
A: 10 - 15 days for compression tooling and 18 - 25 days for LSR injection tooling after drawing approval.

Q3: Can you produce from our sample without a drawing?
A: Yes. We reverse engineer the part, issue a 2D/3D drawing for your approval and then cut the mold.

Q4: Do you provide material test reports?
A: Yes, RoHS, REACH and physical property reports are issued by third-party laboratories such as SGS or Intertek.

Q5: What are your payment and shipping terms?
A: T/T 30% deposit and 70% before shipment, L/C at sight, PayPal and Western Union. FOB, CIF and DDP are all accepted.
