Liquid Silicone Rubber (LSR) has revolutionized manufacturing since the 1970s, offering unparalleled versatility for medical, automotive, consumer, and industrial applications. Its unique properties—biocompatibility, temperature resilience, chemical resistance, and durability—make it ideal for high-performance components. Packson Mold, a leader in precision LSR injection molding since 2006, leverages advanced technology to deliver innovative solutions.
LSR’s inorganic siloxane backbone ensures compatibility with biological materials, excelling in medical devices like respiratory masks and surgical tools. Its compression set resilience suits automotive seals and industrial gaskets, while temperature endurance (-60°C to 180°C) supports applications from dishwashers to EV batteries. The material’s translucency and pigmentation flexibility enable custom designs, and its electrical insulation properties meet stringent industry demands.
High-Volume Efficiency: Fully automated LSR injection molding machines enable rapid production of complex parts with minimal waste.
Consistent Quality: Precision molds crafted via CNC milling and EDM ensure tight tolerances, even for intricate geometries.
Hygienic Production: ISO-certified cleanrooms and automated processes reduce contamination risks, critical for medical and food-grade products.
Durability: Platinum-cured LSR resists chemicals, UV exposure, and extreme temperatures, outperforming traditional elastomers.
Medical: Hypoallergenic, sterilizable components for drug delivery and surgical instruments.
Automotive: Heat-resistant wire harness seals, sensors, and vibration dampeners.
Consumer: Durable kitchenware, baby products, and wearables.
Industrial: Reliable valves and membranes for harsh environments.
With 150+ employees and a 10,000 sqft facility, Packson Mold combines cutting-edge design (CAD/CAM) with robust manufacturing capabilities. Their ISO 9001, ISO 13485, and IATF 16949 certifications underscore a commitment to quality, while Class 7/8 cleanrooms ensure compliance for critical applications.
Material Preparation: Two-component LSR (base + catalyst) is mixed and injected into heated molds.
Precision Tooling: High-grade stainless steel molds withstand abrasion and high temperatures (215°C).
Automated Production: Robotic systems remove finished parts, minimizing human intervention.
Post-Processing: Secondary operations (trimming, assembly) are integrated for seamless workflows.
LSR’s low viscosity allows thin-walled designs without sink marks, while self-adhesive grades simplify over-molding. Packson Mold’s expertise in multi-shot molding and rapid prototyping ensures cost-effective solutions from concept to mass production.
