Four Injection Units, One Clamping Cycle: How Haitian Streamlines Keycap Manufacturing

What do keycap manufacturers fear most?

"Severe color variation—order rejected."

"Noticeable parting lines—poor tactile feel."

"Yield drops to 85% after four separate passes."

All these pain points stem from excessive production steps and high material waste.Market demand has shifted toward multi-color, customized keycaps, yet conventional manufacturing methods struggling to keep up.

Haitian’s MA3600WM/720-570-L380-R280 four-color multi-component injection machine features four coordinated injection units, enabling one-shot molding of multi-color keycaps with a single mold clamping operation.

Three Major Challenges Solved in a Single Cycle

A) Seamless Color Boundaries: Each injection unit achieves injection speeds over 150mm/s. Fast melt filling prevents color bleeding or trailing at color junctions.

B) Consistent Color Quality: High-response servo drives with closed-loop control deliver accurate flow switching and rapid injection response, eliminating color inconsistency.

C) Rotary Table Stability: Imported servo motors with closed-loop control ensure smooth rotation and high repeat positioning accuracy, providing solid mechanical foundation for large-area multi-color molding.

Cut Three Steps, Boost Molding Reliability

By eliminating three rounds of mold changes, parameter tuning, process downtime, and cumulative yield loss, Haitian condenses four steps into a single, seamless cycle. This redefines the quality baseline, pushing yields far beyond the traditional 85% mark.

We take on complex technical challenges with our equipment, delivering higher efficiency and yield to production lines. Samples are available for on-site testing. Visit our company page to send your inquiry 👇 to schedule a mold trial with Haitian.
