How to choose silicone hardness (Shore A)? Correspondence from feel to sealing performance
What is Shore A hardness? Silicone hardness is often expressed as Shore A. The higher the number, the "harder" the silicone. Hardness has a direct impact on: Sealability Extrusion resistance Assembly feel and assembly risk Compression set and life performance (in conjunction with formulation/processing)...
Silicone products common quality problems and solutions: burrs, bubbles, lack of glue, deformation
Silicone products common quality problems: first look at the phenomenon, and then find the root cause Silicone parts of the defects of many and the mold exhaust, temperature and time parameters, raw materials and mold status. The following "phenomenon → common causes → direction of improvement" organization, so that you can do the problem analysis and external instructions. (1) Raw edge (fly...
What standards and testing are required for medical grade silicone products? (Compliance and Quality Essentials)
Why "Medical Grade Silicone" is more than just lip service. Medical applications are not just about the material itself, but also about: Raw material sourcing and consistency Process control Batch traceability Cleaning and packaging Regulatory compliance and test reports This article takes a "purchasing and engineering on the ground" approach to the medical...
How to design O-ring grooves more reliably? Common groove types and assembly points
Why does groove design determine the reliability of an O-Ring? The O-Ring itself is just an elastomer, what really makes it seal is: the contact stresses caused by the amount of compression the groove locates and limits the O-Ring the gap control suppresses the risk of extrusion Therefore, many of the "even if you change the material, it won't work" problems, this is...
How do silicone seals do life verification? Heat Aging, Compression Permanent Deformation and Seal Retention
Why is life verification more important than "no initial leakage"? Many seals behave normally when they are first assembled, but fail after temperature cycling, prolonged pressure, or media immersion. The goal of Life Verification is to expose the risk beforehand under controlled conditions. Key indicators: Compression...
What are the surface processes of silicone products? The choice of spraying oil, feel oil, laser engraving, printing
What are the common surface processes for silicone products? The choice of surface technology is usually a balance between appearance and feel, wear and dirt resistance, cost and delivery. Below with "selection ideas + application scenarios" way to explain. First, first clear the goal you want to solve Just want to look better? (Color consistency,...)
