A silicone part's Shore A hardness can shift after molding due to storage conditions — sometimes enough to affect incoming inspection results. Here's why.

For medical silicone components, mold surface finish is often discussed as a cosmetic or aesthetic specification — how glossy or matte the finished part looks. In reality, for any part that will be sterilized and used in a clinical setting, surface roughness is a functional specification with direct implications for contamination risk, and getting it wrong can mean a part that passes visual inspection but fails to reliably clean and sterilize in actual use.

Liquid silicone shrinks more, and less predictably, than rigid plastic. Learn why, and how mold designers determine the right compensation allowance.

Incorrectly sized vent grooves are one of the most common — and least discussed — causes of trapped-air defects in liquid silicone parts. Here's why.

Batch-to-batch color drift in multi-color silicone parts often traces back to mold runner design, not the color masterbatch. Here's what to check.

A passing first article report isn't the same as a stable mold. Learn the three SPC data points that actually predict long-term production quality.

Mold repair delays can stall an entire OEM order. Compare off-site repair and backup mold dual-track strategies for continuous LSR production.

Somewhere between "let's get a working sample" and "let's place a production order," every buyer sourcing a new silicone part faces a decision that gets surprisingly little attention in supplier conversations: should the mold used to make prototypes also be the mold used for mass production?

Every OEM job hits a first-article or early-production issue sooner or later — a dimensional drift, a cure-related defect, an assembly fit problem. What separates a reliable partner from a risky one isn't whether problems happen; it's how the factory diagnoses and resolves them.
