LSR Gasket Processed by Liquid Silicone Injection Molding

LSR gasket, also known as Liquid Silicone Gasket, Liquid Silicone Rubber Gasket, Silicone Sealing Gasket, which are produced by Liquid Silicone Rubber LSR Injection Molding (LIM) with Liquid Silicone Rubber Material.

Why choose LSR Liquid Silicone Rubber as LSR Gasket Material?

LSR, or liquid silicone rubber, is synthetic resin wherein polymers are joined and structured by chemical bonds that harden permanently after one application of heat.

• High Precision & Mini Parting Line: LSR Gasket compared to common silicone gasket, it is more accurate, with high precision and minimum parting line.

• Material Properties are better than common solid silicone: LSR Gasket has better resistance to high temperatures than thermoplastics; design flexibility, including thick to thin wall constructions; high tear strength; biocompatibility; high chemical resistance; superior compression set value, etc.

• High Production Efficiency & Cost Economic: At first glance, it may be difficult to select LSR as your material of choice because the cost is often higher than other materials. However, LSR Gaskets offers manufacturers many benefits compared to plastics and silicone. As a raw material, the benefits provided by LSR can easily justify its use despite the initial higher cost as manufacturers will have the ability to perform long production runs with minimal labor. Indeed, it is possible to have near complete automatic operation of the process — a single operator can attend to and maintain multiple liquid injection molding machines. This cost saving aspect is extremely important to manufacturers in terms of increased process efficiency who are also faced with the rise in labor costs, making LSR the optimal choice of material for your production needs.

• Despite any perceived shortcomings, LSR Gasket provides manufacturers consistency and cost-effectiveness for a wide range of applications, such as automotive, medical, infant care, electronics and consumer products.

LSR Gasket Application

LSR Gasket is ideal for medical implantables; LSR gaskets and hardware in consumer appliances like: 

• Microwaves

• Electronic interfaces on device keyboards or touchpads

• LSR o-rings

• Wire harnesses

• Coverings

• Stoppers

• Other plastic automotive parts consistently exposed to harsh chemicals and high heat.

In most industrial applications, parts are subjected to harsh environmental conditions where the life time of a component may depend on its seal or gasket. Whether the reason for the seal is to provide water resistance, alignment, dampening, or to withstand high pressures, LSR will excel in maintaining the lifetime requirements of your equipment or parts. With fully automated injection molding processes, improved quality and tight tolerances are achieved, especially when compared to HCRs. Depending on the design of the part, LSR overmolding or LSR 2-Shot (LSR/Thermoplastic) injection molding can provide the precision and quality required while reducing assembly costs.
