Silicone Part Demolding & Automated Removal

Demolding is where many LSR programs lose cycle time and yield. This guide helps product and process engineers understand how silicone parts are released from the cavity and how automation removes them cleanly at high volume-without tearing thin walls or leaving parts behind.

LSR Molding Energy Consumption & Cost per Part

A mid-size liquid silicone rubber (LSR) injection molding machine typically consumes 7-15 kW during production, and servo or all-electric drives cut that by 30-50% versus older fixed-pump hydraulic machines - but electricity is usually only 8-15% of the true cost per part, so buyers should account for material, cycle time, and yield together.

Medical-Grade Silicone Molding: Compliance Guide

Medical-grade silicone molding is the production of silicone components that are safe for patient contact, made from biocompatible liquid silicone rubber (LSR) under a certified quality system in a controlled environment. For device makers, getting compliance right is not optional, it is what makes a part sellable. This guide explains the standards that matter in 2026 and how to verify a supplier meets them.

LSR Injection Molding Cost & Energy: How to Calculate Cost Per Part (2026)

LSR injection molding cost per part is driven mainly by material, cycle time, and energy. This guide breaks down each cost element, shows a sample per-part calculation, and explains how servo drives and cold runners reduce energy and scrap for lower 2026 production costs—useful for engineers and buyers comparing quotes.

LSR Family Mold Design: Producing Multiple Part Geometries in a Single Cycle

Most LSR molders are familiar with multi-cavity molds, which produce many identical parts per cycle. Family molds are different and frequently misunderstood: they produce several different part geometries in a single cycle from one shot of liquid silicone rubber. Used well, a family mold can collapse the tooling investment, machine time, and inventory complexity of a multi-part assembly into one efficient operation.
