Mold Design and Manufacturing Process
At Howmin, we offer a fully integrated production workflow for automotive lighting mold manufacturing, including 2K/3K multi-shot molds and deep-cavity high-precision components.

Product Design
We begin with close collaboration with clients to define product specifications and performance requirements. Our team supports OEM and ODM projects, leveraging expertise in automotive lighting components, such as headlights, tail lights, and lens systems.

UG 3D Modeling
Using advanced CAD software and simulation tools, we conduct mold flow analysis to ensure optimal gate design, cooling system layout, and part filling performance. This step is crucial for multi-shot injection tooling and high-precision mold development.

CAM Program Editing
By utilizing advanced CAM software, we perform dynamic simulation and toolpath programming for 5-axis CNC machining. This allows us to predict and eliminate tool interference and overcut risks before actual machining begins. Through cutting parameter optimization, we greatly enhance machining efficiency and surface finish—ensuring every toolpath is precise, reliable, and ready for the mass production of complex components.

CNC Machining
Mold components are fabricated using our 5-axis CNC machining centers, 6-axis deep-hole drilling machines, and high-speed milling equipment. This allows us to produce tight-tolerance, multi-surface, and deep-cavity mold components for complex automotive parts.

Electrical Discharge Machining
At Howmin, our dual-head EDM machines enable two electrodes to operate simultaneously, allowing for parallel processing of complex mold components. This configuration reduces overall machining cycle time by up to 40%, enhances productivity, and ensures consistent lead times—critical for high-precision automotive lighting mold manufacturing.

Assembly and Calibration
All components are hand-fitted and polished by experienced technicians to ensure high dimensional accuracy. We support insert molding, overmolding, and multi-material mold structures with rigorous in-process quality checks.
