FAQs question mark
Can KingStar Mold handle complex mold designs?2025-07-24T01:58:00+00:00
KingStar Mold has demonstrated consistent capability in executing complex mold designs, with a focus on resolving technical challenges through precision engineering and controlled manufacturing processes.
One of the recent projects was to develop a mold for the housing of a car transmission position sensor. This component has strict functional requirements. The component is made of polyamide 66 (PA66) and is reinforced with 30% glass fibers inside, so the mold must be able to withstand the flow of the worn material. Key features include a central hole with a diameter of 2.5 millimeters (tolerance ±0.015 millimeters) for the sensor insertion; three equally spaced mounting bosses (with a deviation of no more than 0.03 millimeters from the nominal size) to ensure alignment with the transmission housing; and a peripheral chamfer (depth 1.2 millimeters) for fixing the O-ring. To address these issues, the mold was designed as follows:
  • A carbide-tipped core pin for the central bore, hardened to 58–60 HRC to resist wear from glass-filled resin.
  • A servo-driven rotary table for the mounting bosses, enabling in-mold measurement and real-time adjustment of cavity positions.
  • A cam-driven side action with a 0.005mm clearance fit to form the undercut without flash.
After 200,000 production cycles, dimensional checks showed the central bore remained within tolerance, with less than 0.008mm wear on the core pin—validating the mold’s durability.
Another example is a mold for a microfluidic chip manifold used in diagnostic equipment. The part, measuring 45×30×5mm, contained 12 intersecting microchannels (0.3mm width × 0.2mm depth) with surface roughness ≤Ra 0.02μm to prevent sample retention. The mold required:
  • EDM sinking with a 0.1mm diameter electrode to machine the microchannels, achieving a positional accuracy of ±0.003mm between intersecting paths.
  • A temperature-controlled cavity plate (±0.5°C variation) to avoid warpage in the PEEK material.
  • A vacuum-assisted ejection system to release the thin-walled (0.4mm) part without deformation.
First-article inspection using white-light scanning confirmed all channels met geometry specifications, and the mold maintained stability through 50,000 production cycles.
