Zero-Fly Precision Injection Mold - Fanstar Uses Micro-level Sealing Technology To Produce Highly Clean And Highly Reliable Products.

In the fields of medical devices, precision electronics and high-end consumer manufacturing, zero-edge precision injection molds have become an important indicator for evaluating the technical level of mold manufacturers. As a manufacturer specializing in export-grade precision molds, Fanstar has successfully delivered multiple sets of truly "invisible to the naked eye and without any burrs upon touch" zero-edge precision injection molds, which are widely used in high-gloss pen parts, aviation sensor housings, and electrical and mechanical connectors, etc., in scenarios with extremely strict requirements for zero-edge.

The key to the precision injection molds of Zerofei Bin is the micrometer-level control of dynamic mating parts such as the parting surface, slider, inclined top, and ejector pin. Fanstar uses five-axis linkage ultra-precision processing to ensure that the parting surface flatness is ≤ 0.005mm, and the mating clearance is strictly controlled within 0.01mm. The mold steel is selected from high-purity S136 or 420 stainless steel and undergoes mirror polishing (Ra ≤ 0.1μm) and anti-sticking coating treatment to enhance sealing and demolding stability. At the same time, through Moldflow analysis, the depth of the exhaust groove is optimized (usually ≤ 0.02mm), ensuring no flash while guaranteeing adequate exhaust. In pen molds, transparent high-gloss parts can be directly assembled without any trimming; in aviation molds, they meet the no-particle shedding requirements in ISO 14644 cleanroom environments; for electromechanical shell molds, the connector insertion and extraction lifespan and signal integrity are ensured not to be interfered by burrs.

All Zero-Fly Precision Injection Molds are equipped with automated production and full inspection processes, significantly reducing post-processing costs and quality risks.
