Twin-cavity injection mold with hot-runner manifold and hydraulic cores for a vehicle coolant reservoir — uniform wall thickness with in-mold water circuits.
Structural member mold with sequential valve gating — weld lines moved off all cosmetic faces; runs on presses up to 320 T.
Over-molding tool for interior trim — a second material is molded over the substrate in one tool, with eight angled lifters releasing every undercut in a single stroke.
Valve-gated hot runner on eight cavities — zero gate vestige on any visible face.
Long-stroke sliders form the 45° channel in one shot — no secondary machining.
Brass inserts loaded in-mold; a two-stage core pull forms the elbow and locking fingers.
Gas-assist injection molding with hydraulic core pull — the high-pressure nitrogen hollows out the PA6-GF30 manifold, leaving a smooth inner passage.
Medical-grade transparent manifold tool, cavities polished to SPI A1 for scratch-free clarity.
One large automotive-parts mold shown from both sides — hydraulic cores and water-assist channels plumbed and proven in-house.
Two-color (2K) connector mold — four cavities mold hard PA66 housing and soft seal in one shot, no assembly needed.
Balanced hot runners and an 8-second cycle on sixteen preform cavities.
Two-plate shell tool for power-product accessories — high-gloss cosmetic faces plus grain texture built into one mold.
Locked process windows, real-time SPC and a direct line to the factory floor.
