The dimensional stability of products, especially when designed to integrate with other pieces, is critical. We maintain ultra-tight tolerance windows so that multi-part devices integrate and function as intended. Mold-Town monitors injection molding processes and parts for issues at every stage. Our quality systems will detect and reveal even the slightest signs of defects in injection molding, including:

• Flow Lines. While these wavy lines that develop from varied material cooling speeds are unlikely to affect the functionality of a part, they do affect the aesthetics.
• Discoloration. Discoloration from suboptimal mixing or a lack of thermal stability doesn’t impact the integrity of a component, but it will present an undesirable color abnormality on a portion of a molded part.
• Burning. The result of trapped gases within the mold, discolored burn marks on a component range from being unsightly to causing material deterioration.
• Air Bubbles. Depending on the amount or size of trapped pockets of air within a component when there is insufficient mold pressure, air bubbles can be anything from a minor issue to one that weakens the entire part.
• Warping. Warping can occur as molded components are cooling and, if that process occurs too rapidly, the material will shrink in an uneven manner and possibly hinder integration into larger assemblies.

Upon early detection, our process-wide quality systems analyze the most likely cause of a defect and modify our methods accordingly.
