Liquid Silicone Rubber Applications: Industries & Use Cases Guide

Liquid silicone rubber applications span almost every serious manufacturing sector — from implantable medical devices to EV battery seals to baby-bottle nipples to dielectric encapsulation in smartphones. This guide maps where liquid silicone rubber wins, why it wins there, and…
Silicone Overmolding: Multi-Material LSR Design Guide [2026]
![Silicone Overmolding: Multi-Material LSR Design Guide [2026]](https://meitu-engelhardt.com/wp-content/uploads/2026/04/0-8-768x512.png)
Silicone overmolding is a manufacturing process that bonds a flexible silicone layer to a rigid plastic part or metal substrate, all in one shot of the overmolding process. Two materials-the ease of a thermoset silicone on the “soft” side plus…
LSR Design Guidelines: Wall Thickness, Tolerances & DFM

What design engineers need to know before locking geometry — first-party tolerance data and decision rules from a Class 7 LSR cell producing 1,000+ tons per year. These LSR design guidelines answer the questions that matter before a single mold…
Silicone Compression Molding: Process, Applications & When to Use It

Silicone compression molding shapes pre-measured high-consistency rubber into cured parts inside a heated, closed mold — at a fraction of the tooling spend that liquid silicone rubber (LSR) injection demands. Silicone rubber compression molding is a manufacturing process that begins…
LSR vs TPE: When to Choose Silicone Over Thermoplastic Elastomers

LSR vs TPE is the elastomer-selection question that dooms most product teams before a single part is tooled. Both liquid silicone rubber (LSR) and thermoplastic elastomer (TPE) displace natural rubber in the most demanding precision applications, yet they occupy opposite…
LSR vs HCR Silicone Rubber: A Side-by-Side Material & Process Comparison for Engineers

Engineers comparing LSR vs HCR silicone rubber for a new program rarely settle the question on chemistry alone. The decision usually turns on cycle time at target volume, achievable tolerance against the part drawing, the post-cure burden downstream qualification can…
Rubber Overmolding: Process, Design Tips & 2026 Applications

Rubber overmolding bonds a vulcanized rubber or liquid silicone elastomer directly onto a metal or plastic substrate in one molding cycle. It replaces a secondary assembly step and removes the adhesive joint that shows up in most field warranty claims.…
Rubber Molding Tolerances Explained: Standards, Classes, and How to Specify Them

A Rubber molding tolerance describes the allowable variation in dimension that a molded rubber part may exhibit of its nominal dimension – and they behave nothing like the machined-metal tolerances most design engineers grew up with. At Meitu-Engelhardt, we see…
How Much Does Custom Rubber Molding Cost? A 2026 Pricing Guide for OEM Buyers

Molded rubber cost for custom parts in 2026 lands somewhere between $0.15 and $100 per piece, with tooling spanning $800 for a single-cavity prototype mold up to north of $50,000 for a hardened multi-cavity production tool. An honest answer to…
Rubber Molding Methods Comparison: How Compression, Transfer, and Injection Stack Up

This comparison of three rubber molding methods cuts through the marketing fluff, comparing the numerical data that drives engineering and procurement decisions today: cure temperatures, cycle times, tooling cost ranges, RMA tolerance classes, waste behavior, and the volume crossover where…
