[01] Products Reference · 產品簡介
Products shown are OEM references for display only and are not for sale. They illustrate the range of parts we produce for our customers.
[01] 雙色注塑產品
Grand Long has leading-edge technology in double injection developed over recent years. Two-shot tooling and moulding let us combine hard and soft materials, or two colours, in a single automated cycle — fewer parts, no assembly, better feel.
[02] 精密注塑產品
Since the company's establishment, Grand Long has produced a wide variety of precision plastic parts and components for more than 30 years — including optical-grade clear parts, fine mechanical components and technical assemblies.
[03] 後加工工藝
Our in-house decorating workshop finishes parts to a market-ready standard, so what leaves our plant is a finished product rather than a raw moulding.
