Why Choose LSR Silicone Mold for Your Medical Silicone Products

Design and engineering support to help you turn ideas into manufacturable products.

Flow Channel Design

Optimize flow channels to achieve uniform and rapid filling of liquid silicone, preventing bubbles and defects while ensuring balanced pressure and flow.

Venting System

Design effective venting paths to prevent gas buildup during curing, which could affect product integrity.

Temperature Control

Equip the mold with precise temperature control systems to maintain consistent internal temperature and promote uniform silicone curing.

Material Selection

Use high-hardness, wear-resistant, and thermally conductive materials such as premium steel and nickel alloys.

Demolding Design

Consider demolding angles and mechanisms to ensure easy product release without damaging smooth surfaces.

Mold Structure

Select two-plate or multi-plate mold structures based on product requirements to support complex geometries.

Precision Machining

Utilize CNC machines and other high-precision equipment to ensure smooth mold surfaces and accurate dimensions.

Exceptional Purity & Biocompatibility (Safety First)

In the medical field, whether a material causes irritation or toxicity is the top priority.

Platinum-cured with no residue

Liquid silicone rubber (LSR) uses platinum-catalyzed curing, a highly stable chemical process. In contrast, solid silicone often uses peroxide curing, which may generate by-products such as odor or extractables.

Authoritative certifications

LSR is more likely to pass strict medical-grade certifications such as USP Class VI, ISO 10993 biocompatibility tests, and FDA food-contact standards.

Sterilization-friendly

LSR can withstand multiple sterilization methods, including autoclave, ETO, and more—without degrading or releasing harmful substances.

Micron-Level Precision Molding (Detail Replication)

Medical devices often feature complex structures and miniature dimensions. LSR mold manufacturing excels in this area

Outstanding flowability

Before curing, LSR has very low viscosity and easily fills micro-scale mold structures, perfectly replicating every detail.

Ultra-thin wall molding

Capable of producing thin-walled parts as small as 0.1–0.3 mm (e.g., precision catheter tips, micro sealing rings)—something hard for solid silicone to achieve.

Dimensional stability

LSR offers extremely low shrinkage (0.1%–0.3%), and precise mold temperature control (±10°C), ensuring exceptional dimensional consistency—critical for medical components requiring tight fits.

Fully Automated Production & Zero Flash (Cleanliness)

Medical products are typically produced in cleanrooms, and LSR injection molding fits perfectly with these requirements.

No flash or burrs

LSR injection molding (LIM) uses high-pressure injection into closed molds, resulting in minimal flash at parting lines. Solid silicone compression molding often produces burrs requiring manual trimming, which increases cost and may create risks (e.g., loose particles).

High automation

From material mixing to injection, molding, and part removal, the entire process can be fully automated. This reduces contamination risks and meets cleanroom standards (e.g., Class 100,000).

Excellent Physical Properties & Skin-Friendly Feel

Skin-like softness

LSR typically has a soft hardness range (Shore A 0–50°), offering a silky, flexible touch with excellent elasticity—ideal for contact with human skin or mucous membranes, reducing patient discomfort.

Sealing & corrosion resistance

It provides superior waterproof sealing performance and strong resistance to body fluids and disinfectants. Whether for long-term use or implantation, LSR maintains stable performance.
