LSR Overmolded Steel Component for Sealing and Impact Protection

Built for industrial machinery components, mechanical sealing and protective covers, and automotive structural and damping parts, LSR Overmolded Steel Component for Sealing and Impact Protection is a silicone sealing component centered on base material: Iron / Carbon Steel; overmold material: Liquid Silicone Rubber (LSR); process: Metal Overmolding Injection. This configuration is intended for buyers who need a production-ready part rather than a generic off-the-shelf silicone item.

The component should be evaluated around its assembly function rather than as a generic silicone item. This makes it easier to compare drawings, confirm process feasibility and identify the characteristics that should be controlled during production.

What the Component Is Designed to Do

• Enhanced load-bearing capacity
• Strong mechanical rigidity
• Developed for structural and functional components
• Reduces vibration transmission
• Helps protect metal parts and assemblies
• Improves long-term mechanical reliability
• Dust and moisture resistance

Construction and Process Details

Intended Equipment and Product Uses

Points to Review During Qualification

• The product is manufactured using precision metal overmolding technology:
• Metal Part Fabrication Iron or carbon steel components are machined or stamped into required shape.
• Surface Treatment Cleaning, sandblasting, or chemical treatment improves bonding performance.
• LSR Injection Overmolding Liquid silicone rubber is injected onto the metal surface.
• Thermal Curing Silicone is cured to form a permanent bonded protective layer.
• Final Inspection Adhesion strength, sealing performance, and dimensional accuracy are tested.

Buyer FAQ

Why use iron instead of aluminum or stainless steel?

Iron provides cost-effective high strength and is suitable for heavy-duty structural applications.

Does the silicone layer prevent rust?

Yes, the LSR coating isolates the metal from moisture and air, significantly reducing corrosion risk.

Can this product be used outdoors?

Yes, it is suitable for outdoor and industrial environments with proper design.
