Even the most reputable overseas factories often leave you with one or more of the following pain points:
- High Unit Price – Average LSR part cost in China is 12‑15% above European‑grade suppliers due to hidden tooling fees.
- Long Lead Times – Typical 6‑8 weeks from order to delivery, which stalls product launches.
- Inconsistent Dimensional Tolerance – ±0.15 mm variance leads to re‑work and scrap rates up to 8%.
- Expensive Freight – 30‑45% of total landed cost for 40‑ft containers shipped from Asia to the US/EU.
- Regulatory Uncertainty – Lack of CE, FDA, or ISO‑9001 certification creates market entry barriers.
According to Grand View Research, the global LSR market will reach USD 4.97 billion by 2030 – a clear sign that demand for high‑quality silicone parts is exploding, but only manufacturers that can guarantee speed, cost, and compliance will capture the upside.
See How We Solve ItOur Injection Compression Molding Edge – Technical Superiority & Business Benefits
Guangdong Yingtai High Precision Technology Co., Ltd. combines 55 liquid‑silicone molding machines with 80 automatic plastic injection units in a 35,000 m² smart factory. The result is a production platform that delivers:
- Up to 40% faster cycle times thanks to patented compression‑assist technology.
- ±0.05 mm dimensional stability verified by our in‑house CMM (Coordinate Measuring Machine).
- ISO 9001, CE, FDA, RoHS, GS, and VDE certifications for every batch.
- OEM/ODM design support from concept to tooling within 3 weeks.
- Direct sea‑air logistics hub in Shenzhen reduces freight to US $1.20/kg on average.
Key Technical Parameters (Injection Compression Molding)
| Parameter | Typical Range | Impact on Part Quality |
|---|---|---|
| Material Type | LSR (Medical‑grade, Food‑grade), PC/ABS, TPU | Biocompatibility, chemical resistance, flexibility |
| Injection Pressure | 80‑150 MPa | Fills intricate cavities, reduces flash |
| Compression Ratio | 1.2‑1.6 : 1 | Improves surface finish, lowers sink marks |
| Cycle Time | 3‑7 s (high‑speed), 12‑20 s (large parts) | Higher throughput, lower energy cost |
| Curing Temperature | 150‑180 °C (LSR), 200‑240 °C (thermoplastics) | Ensures complete cross‑linking, dimensional stability |
| Tooling Material | P20 steel, Beryllium‑copper, Al‑Si alloys | Tool life 2‑5 M cycles, precision <0.02 mm |
| Gate Design | Cold‑runner, hot‑runner, valve‑gate | Controls flow front, reduces weld lines |
Application Scenarios & Case Studies
Medical Device Seals – A leading US med‑tech firm needed 10 k silicone gaskets for a wearable insulin pump. Using our low‑temperature cure LSR, we cut the lead time from 9 weeks to 2 weeks, while maintaining ISO 13485 compliance. Result: 22% cost reduction and zero‑defect launch.
Automotive Interior Over‑molded Touch Panels – A European OEM required 250 k over‑molded soft‑touch modules. Our dual‑shot compression‑injection process combined LSR with ABS, delivering ±0.03 mm flatness and a 15% weight saving.
Consumer Electronics Waterproof Seals – A Chinese smartphone brand sourced 500 k water‑resistant silicone rings. Our vacuum‑assisted compression molding eliminated air entrapment, reducing flash waste from 4% to <0.5%.
Frequently Asked Questions
What is the difference between injection compression molding and traditional injection molding?
Injection compression molding adds a controlled compression stroke after the cavity is filled, which reduces sink marks, improves surface finish, and allows lower injection pressures. Traditional injection molding relies solely on high pressure to fill the cavity, often leading to higher flash and more post‑processing.
Can you produce OEM designs with proprietary tooling?
Yes. Our engineering team offers full‑cycle OEM/ODM services. We can design, prototype (using rapid‑tooling), and produce up to 5 M‑cycle steel molds. Tooling cost is amortized over the production run, and we provide a free 3‑D CAD review within 48 hours.
What are the typical payment terms for international buyers?
Standard terms are 30 % T/T deposit, 70 % against copy of Bill of Lading. For qualified buyers we offer L/C at sight, or PayPal/WhatsApp Pay for sample orders.
How do you ensure regulatory compliance for medical‑grade LSR parts?
All medical‑grade runs are processed in ISO 13485‑certified clean rooms, with material traceability, biocompatibility testing (ISO 10993‑1), and CE/FDA documentation provided on request.

What logistics options are available for fast delivery?
We operate a dedicated air‑freight lane from Shenzhen to major US/EU hubs (NY, LA, Rotterdam, Frankfurt). For high‑volume orders, we consolidate sea‑air containers that reach the destination within 12 days after loading.
