South China Pen Mold Manufacturer - Fanstar Leads The Stationery Injection Mold Market with High-Quality And Efficient Solutions

As a South China pen-type multi-hole mold manufacturer rooted in the Guangdong-Hong Kong-Macao Greater Bay Area, Fanstar, with over a decade of concentrated technical accumulation in pen-type precision molds, has become a trusted partner of globally renowned stationery brands. We focus on solutions for multi-hole molds of pen types in South China ranging from 8 holes to 64 holes, featuring high gloss, fully automatic operation, no pin marks, and concealed injection. These solutions help our customers achieve efficient production, zero adjustment, and large-scale manufacturing.

In the manufacturing of high-end pens, both appearance quality and production efficiency are indispensable. Fanstar uses imported S136 mirror steel, and the cavity polishing reaches the SPI-A1 standard (Ra ≤ 0.01 μm), ensuring that the transparent or metallic texture pen shafts are formed without any flow marks or weld lines during one-time molding; through Moldflow flow analysis, the precise optimization of the flow channels and the layout of the injection points is carried out, and the uniformity error of the 64-hole filling is controlled within 3%; the mold integrates pneumatic push plates or servo ejection systems, which are compatible with high-speed injection machines, and the single mold cycle can be stably controlled within 8 seconds, with the production yield exceeding 98%. At the same time, complex functions such as the pressing mechanism, spring chamber, pen clip latch, etc. are integrated into one molding process, eliminating the need for secondary assembly.

Apart from its core strength of being a manufacturer of multi-hole molds for pen products in South China, Fanstar also has extensive experience in areas such as aerospace molds (using PEEK/LCP high-temperature materials) and mechanical and electrical enclosure molds (with IP67 protection, multiple sliders, and V0 flame-retardant level). It offers a one-stop service ranging from DFM review, mold flow simulation to clean prototype testing.

Choosing Fanstar means choosing a manufacturer in South China that truly understands the structure of writing tools, possesses advanced multi-hole processing technology, and can respond promptly to orders. We offer high-quality, cost-effective and reliable injection mold solutions for writing tools, leveraging our engineering precision and localized manufacturing advantages.
