Accelerate Your Production with Small Scale Injection Molding – Ready in 30 Days, Zero‑Risk Sample
Small scale injection molding delivers high‑precision, low‑volume silicone and plastic parts for medical, automotive, and consumer‑electronics markets. You no longer need to wait months for large‑batch tooling—our Dong‑guan factory can prototype and launch up to 5,000 units per month while keeping unit costs under $2.30. Your engineering team gets the exact geometry, surface finish, and material compliance they demand, and you secure a fast ROI.
Why Your Current Sourcing Strategy Is Costing You
1. High Price, Low Margin – Traditional overseas molds charge $15‑$30 k for a single cavity, pushing per‑part cost above $5 for volumes under 10 k.
2. Slow Delivery Speed – Shipping from China to the U.S. or EU can take 4‑6 weeks, and customs clearance adds another 5‑7 days, delaying product launches.
3. Poor Quality Consistency – Without rigorous material characterization, LSR parts suffer flash, shrinkage, and dimensional drift of up to ±0.15 mm, causing re‑work rates of 8‑12 %.
4. Expensive Shipping & Tariffs – Freight rates have risen 23 % YoY, while 25 % duties on certain silicone goods erode profitability.
5. Lack of Technical Support – Suppliers often provide only basic data sheets, leaving you to guess optimal cure cycles and gate designs.
According to the Grand View Research LSR market report (2023), the sector will grow to $4.97 B by 2030, yet 70 % of buyers cite “tooling lead time” as the biggest barrier. If you keep paying for large‑scale molds you’ll miss the next wave of high‑value, low‑volume products.

|---|---|---|
| Clamp Force | 150 – 350 ton | Ensures cavity stability for thin‑wall LSR parts (≤0.3 mm) |
| Shot Size | 0.5 – 5 g | Optimized for low‑volume runs, reduces material waste to ≤2 % |
| Injection Speed | 30 – 120 mm/s | Controls shear heating; critical for biocompatible medical grades |
| Cure Cycle | 8 – 20 s (high‑temp); 20 – 45 s (low‑temp) | Fast cycles enable up to 30 pcs/min for consumer electronics seals |
| Material Compatibility | Medical‑grade LSR, Food‑contact LSR, RTV, TPE, PP, PC | Meets FDA 21 CFR 177.2600, EU REACH, and ISO 10993‑1 standards |
| Gate Types | Pin, Edge, Sub‑Gate, Vacuum‑Assist | Customizable for micro‑fluidic devices and optical lenses |
| Temperature Control | Room → 250 °C (±0.5 °C) | Ensures consistent cure for high‑temperature automotive seals |
Application Scenarios & Real‑World Cases
Medical Devices – 0.2 mm wall‑thickness catheters, biocompatible LSR seals for insulin pumps, and optical lenses with ±0.02 mm tolerance.
Automotive – Over‑molded waterproof gaskets for EV battery enclosures, surviving −40 °C to +150 °C cycles.
Consumer Electronics – Soft‑touch buttons for wearables, flash‑free silicone keys for smartphones.
Industrial Appliances – Chemical‑resistant seals for pump housings, rated for 5 MPa pressure.
A recent ResearchNester study (2025) shows that 38 % of new medical‑device launches rely on small‑batch LSR molding for rapid market entry. Our pilot line in Dongguan delivered a 3‑k unit run of a silicone‑overmolded hearing‑aid housing in just 12 days, cutting time‑to‑market by 68 %.
Frequently Asked Questions
What is the minimum order quantity for small scale injection molding?
We accept runs as low as 500 pcs for standard LSR grades. For highly customized molds, the MOQ is 1 k pieces to ensure cost‑effective tooling amortization.
Can you provide material certification for medical‑grade LSR?
Yes. Every batch is accompanied by an FDA 21 CFR 177.2600 certificate, ISO 10993‑1 biocompatibility report, and a Material Safety Data Sheet (MSDS).
How long does tooling take for a 2‑cavity silicone mold?
Standard steel molds: 14‑21 days. For rapid‑prototype aluminum molds, we can deliver in 7 days, ideal for pilot production.
What are the shipping options and lead times to the U.S. and EU?
We offer DDP (Delivered Duty Paid) via air freight (3‑5 days) for urgent orders and sea freight (20‑25 days) for bulk shipments. All customs duties are pre‑paid.
Do you provide post‑production support and warranty?
Yes. Every part comes with a 12‑month warranty against material defects. Our technical team offers free troubleshooting and a 30‑day replacement guarantee for any out‑of‑spec batch.
Limited‑Time Offer: Free Sample & 5 % Discount on First Order
Place a pilot order within the next 10 days and receive a complimentary sample of your chosen silicone grade, plus a 5 % discount on the tooling cost. No upfront payment required – we accept a 30 % T/T deposit and the rest on delivery.
- Free technical consultation (30 min)
