Howmin designs and builds multi-shot injection molds—also known as bi-injection, double-injection, or 2-component (2C) tooling—from single-shot to four-shot (4K) systems. The key technical challenges of multi-color mold manufacturing lie in precise core alignment, shrinkage compensation across different resins, and deep mold design expertise. This is where Howmin's 30 years of hands-on experience delivers real value: high precision, stability, and reliable performance in complex multi-shot applications. Howmin is one of the few mold makers in Taiwan capable of delivering four-shot (4K) automotive lamp molds.

OUR CORE SERVICES

01
CNC Precision Machining
Howmin is equipped with large-format 5-axis CNC machining centers featuring high speed and high rigidity, specifically designed for machining deep cavities, complex freeform surfaces, and high-precision areas in automotive lighting molds. This advanced equipment significantly enhances machining quality and extends mold service life, making it especially suitable for high-complexity plastic injection molds and multi-shot mold applications.

02
Lighting Mold Development
We utilize advanced UG (Unigraphics) CAD software for automotive lighting plastic mold design, supporting single-shot, two-shot (2K), three-shot (3K), and four-shot (4K) injection mold development with strong multi-material integration capabilities. Through real-time collaboration and reverse engineering support, we significantly enhance mold structural accuracy and design efficiency, while effectively shortening the automotive lighting mold development cycle and accelerating time-to-mass production.

03
Mold Assembly & Die Spotting
With over 30 years of mold-making experience, our team specializes in mold assembly, hand fitting, polishing, and die spotting. Every mold goes through rigorous fitting and validation to ensure optimal parting-line sealing and stable mass production—trusted by automotive lighting OEMs and custom tooling clients.
