Liquid silicone rubber (LSR) injection moulding machines are specialised equipment designed to process two-component liquid silicone systems that cure through platinum-catalysed reactions. These machines feature precise metering systems, temperature-controlled processing, and contamination-free material handling to produce high-quality silicone components for demanding applications.
Modern LSR machines incorporate advanced mixing technology, closed-loop material systems, and precise injection control to ensure consistent material preparation and curing. These systems are essential for medical device manufacturing, automotive sealing applications, and consumer products requiring biocompatible, temperature-resistant, and chemically inert silicone components.
LSR injection moulding machines typically range from small precision units with 15-tonne clamping force to large systems exceeding 400 tonnes, with specialised material handling systems for two-component liquid silicone processing. Precise metering pumps maintain accurate A:B component ratios, typically 1:1 or 10:1, whilst temperature control systems manage material viscosity and prevent premature curing.
Closed-loop material systems prevent contamination and moisture exposure that could inhibit platinum catalyst systems. Static or dynamic mixing ensures homogeneous material preparation before injection, whilst heated manifold systems maintain optimal processing temperatures throughout the injection cycle. Mould heating systems, typically 160-200°C, provide controlled curing conditions for consistent part properties.
These machines excel in producing parts with complex geometries, thin walls, and precise dimensional requirements through controlled injection parameters and optimised curing cycles. Cycle times are typically faster than compression moulding, ranging from 30 seconds to several minutes depending on part thickness. Advanced systems include material conditioning, automatic colour changes, and integrated quality monitoring for pharmaceutical and medical applications.
LSR injection moulding machines serve high-performance silicone component manufacturing across demanding industries, including:
PlastikCity connects you with vetted LSR injection moulding machine suppliers across the UK and Ireland. All suppliers in our network undergo rigorous assessment where we verify financial stability, service quality, and reputation to ensure you connect with reliable, professional partners.
Submit one enquiry and receive quotes from multiple LSR injection moulding specialists. This saves significant time compared to contacting suppliers individually whilst ensuring competitive pricing. The service is completely free for buyers with no hidden costs or commissions.
LSR machines feature specialised two-component metering systems, closed-loop material handling, heated moulds (160-200°C), and contamination-free processing. Unlike thermoplastics, LSR undergoes chemical curing rather than cooling solidification.
Common mixing ratios are 1:1 and 10:1 (Part A to Part B), with precise metering pumps maintaining accuracy within ±1%. Some specialised formulations may use different ratios depending on application requirements and material properties.
Typical mould temperatures range from 160-200°C with curing times from 30 seconds to several minutes depending on part thickness. Thicker sections require longer cure times to ensure complete crosslinking throughout the part geometry.
Contamination prevention includes closed-loop material systems, moisture exclusion, clean processing environments, and avoiding contact with sulfur, amines, and other catalyst inhibitors. Some applications require clean room processing conditions.
Cycle times typically range from 30 seconds to 3 minutes depending on part thickness, geometry, and cure requirements. LSR generally cures faster than compression moulded silicone due to higher processing temperatures and pressure.
Yes, though material changeovers require thorough system purging to prevent cross-contamination. Some machines include automated material switching capabilities, whilst colour changes typically require dedicated material supply systems.
