Your Fast‑Track to High‑Precision Silicone Parts
Collapsible core injection molding eliminates long cooling cycles, cuts material waste, and delivers ultra‑tight tolerances for medical, automotive, and consumer‑electronics applications.
Why Your Current Molding Process Is Costing You
- Excessive Cycle Times: Traditional rigid‑core molds require up to 30 seconds of cooling per cavity, inflating labor costs by 25 %.
- High Scrap Rates: Inconsistent core ejection leads to flash and dimensional drift – average waste of 0.8 kg per 1,000 parts.
- Limited Design Flexibility: Complex internal channels (e.g., fluidic pathways) are impossible without costly multi‑shot tooling.
- Slow Time‑to‑Market: Tooling revisions take weeks; your product launch window shrinks by 2‑3 months.
- Unpredictable Shipping Costs: Heavy, bulk‑packed rigid‑core parts increase freight by up to 15 % per container.
According to the Grand View Research LSR market report, the global LSR market will reach USD 4.97 billion by 2030—driven largely by manufacturers who adopt faster, waste‑free processes like collapsible core injection molding.
Collapsible Core Injection Molding – The Competitive Edge
Core Advantages
- Up to 40 % Faster Cycle Times – the core retracts instantly, eliminating cooling bottlenecks.
- Zero‑Flash Design – precision‑engineered split cores prevent material leakage.
- Reduced Material Waste – up to 30 % less LSR consumption per part.
- Multi‑Material Overmolding – seamlessly combine LSR with ABS, PC, or TPU in a single shot.
- Scalable Production – from 5 k to 500 k+ units per year without re‑tooling.
- ISO‑Certified Quality – ISO 9001, ISO 13485 (medical), CE, FCC compliance.

Frequently Asked Questions
What is collapsible core injection molding?
It is a silicone‑injection process where the core splits or retracts during molding, allowing instant cavity opening, faster cycles, and zero‑flash parts.
Can I use the same core for different part geometries?
Yes. Our modular core system lets you swap split sections within 30 minutes, supporting up to 12 design variants per tooling set.
What material grades are compatible?
Medical‑grade LSR (ISO 10993), automotive‑grade LSR, RTV, PDMS, and hybrid LSR/ABS or LSR/PC blends.
How long does tooling take?
Standard steel split‑core molds are delivered in 6‑8 weeks; aluminum rapid‑tool options are ready in 3‑4 weeks.
What are the logistics and payment terms?
We ship via DHL/FedEx (air) or Maersk (sea). Payment: 30 % T/T upfront, 70 % upon shipment. For repeat orders, we offer net‑30 credit.
Do you provide after‑sales support and warranty?
All parts come with a 12‑month warranty against material defects. Our technical team offers 24/7 remote assistance and on‑site troubleshooting if needed.
Ready to Accelerate Your Production?
Limited‑time offer: First 100 pcs of any collapsible core part shipped free of charge (shipping cost covered). No minimum order.
