Silicone mold shrinkage is the gap between the cavity you cut and the part you get, and it is the most common reason a first article fails a dimensional check. The percentage is small — typically 1.5% to 3% — but on a 150 mm enclosure that is up to 4.5 mm of missing part, […]

HTV Compression vs LSR Injection Molding: How to Choose the Right Food-Grade Silicone Mold Process? Selecting the wrong silicone molding process causes high tooling costs and low production efficiency. You need a clear selection guide for your project. HTV compression molding suits low-volume, large-size, and simple products at lower tooling costs. LSR injection molding suits […]

Why Proper Silicone Mold Cleaning Matters Food-grade silicone used for repeated food contact should follow U.S. requirements for rubber articles intended for repeated use. Under FDA 21 CFR 177.2600 – Rubber articles intended for repeated use (eCFR), permissible silicone elastomers, adjuvants, vulcanizing agents and extractive limits are defined, and finished articles must be thoroughly cleansed […]

How to Understand the Impact of Silicone Mold Structure on Product Quality? Incorrect mold design causes air traps and tearing defects. Ignoring mold details leads to soaring scrap rates during mass production. A silicone mold structure consists of top plates, bottom plates, cores, and ejector plates. Proper layout, precise parting lines, venting channels, and R […]

What Is HTV Silicone, and How Does It Function in Silicone Manufacturing? Confused between HTV, LSR, and RTV silicones during sourcing? Selecting wrong materials inflates tooling budgets and triggers product rejections. HTV Silicone is high temperature vulcanizing silicone rubber. Originating as a dense solid compound of base gum and fumed silica, it crosslinks under 160°C […]

What Are the Dangers of BPA, and Which Silicone Products Contain It? Are you concerned that baby tableware and heating utensils leach bisphenol A? Ignoring material compliance hazards exposes your family to hidden chemical risks. Bisphenol A is a harmful plastic monomer that disrupts human endocrine function. Pure silicone is naturally free from bisphenol A. […]

What is the Difference Between Platinum-Cured Silicone and Regular Silicone? Concerned about odors and toxic residues in silicone products? Choosing the wrong curing system leads to quality returns. Understanding chemical differences guarantees safe material selection. The primary difference lies in the curing mechanism. Platinum-cured silicone uses addition catalysis, leaving virtually no chemical byproducts or odor; […]

Why Does New Food Safe Silicone Smell and How Do You Remove It? Does a strange rubber smell on new silicone cookware make you hesitate to cook? Chemical odors raise safety concerns. Ignoring odor sources risks using harmful fake materials. Pure cured silicone is virtually odorless. New product smells come from residual vulcanizing agents, release […]

What is fda silicone ? How to Meet FDA Standards Correctly? Purchasing unverified silicone leading to regulatory fines and customs seizures? Obscuring compliance rules destroys your brand reputation. fda silicone refers to silicone rubber that complies with United States Food and Drug Administration (FDA) regulations.
