An independent temperature loop at the gate switches setpoints across filling, packing, and cooling stages, then freezes the gate to break the melt before mold opening.

GATE DEFECTS
All three occur where the tip meets the gate. Identify the type first, then set gate temperature and the break-off point from the material and molding cycle.
Problem: A thin thread is drawn between the tip and the gate as the mold opens; the break is not clean and the thread lands on the part or the mold.
Our solution: Independent gate temperature control, with the cooling-stage temperature set to the material and cycle so the gate freezes before the mold opens.

Problem: Melt out-of-control at gate, resulting in continuous dripping and flash that builds into a slug over several shots.
Our solution: Gate temperature drops with the cycle, so the exit section solidifies before the mold opens and no continuous dripping or flash remains.

Problem: Residue blocks the gate channel, flow drops until no material comes out and the line must stop for cleaning.
Our solution: Independent gate temperature control to avoid local cold spots, plus radiused runners that reduce residue hold-up and limit carbonization.

Confirm whether the runner can gate the part, then check gate marks and purging needs. Full specifications for all four series are in the product center.
TECHNOLOGY
The whole runner does not heat and cool. Temperature changes only at the tip and gate, switched within one molding cycle.
APPLICATIONS
Materials, gate locations and tolerance requirements vary by industry, and so do the common defect types. Determine the direction from the most common defect in your industry, then match the nozzle and gating.
PA66+GF / PA9T / PA6T / PPS / LCP
Multi-cavity connectors are prone to stringing and dimensional drift; runner cleanliness must hold after colour changes.
LCP / PPS+GF / PA9T
Thin-wall, multi-cavity high-speed connectors: a blocked gate can scrap the whole tool and stop the line.
PC / PC+ABS / PMMA / PBT / LCP
Cosmetic parts cannot show gate marks, while thin walls also demand stable flow.
PP / PS / COC/COP / PC / PEEK / PSU
Repeatedly sterilised parts cannot show black specks or leachables, and gate residue should be removable.
PEI / PEEK / PSU / PPS / PA46
High-heat parts run in small batches with frequent material and colour changes; carbonised residue easily clogs the gate.
FROM DESIGN TO VALIDATION
Send part drawings, material grade, mold layout and molding conditions; we issue the proposal from the layout. Once approved, the order is placed, the assembly is completed in Dongguan and shipped to site, where our staff support installation and on-machine validation.
Same day
Send part drawings, material grade, mold layout, cavity count and molding conditions; once complete, a feasibility judgement is issued the same day.
2 working days, 1–2 days joint review
The layout defines runner routing, nozzle type and temperature control; drawings are then reviewed with the customer's mold engineer until the tool is ready to open.
20–25 working days
After order confirmation, material is cut, machined, assembled and powered up; every channel is temperature-verified before the assembly ships.
Half a working day
We install and wire the system on site, support parameter tuning and hand over once consecutive parts run stable.
Lead times above apply to standard molds and operating conditions with imported parts arriving on schedule. If imported parts are short or a customer specifies a brand, lead time is quoted separately.
Proposals and commercial work are handled in Shenzhen; machining and assembly in Dongguan; the assembled system then ships to the customer site.
Register the basic project details. Our engineers will review the part, mold and material, then provide a proposal and quotation.
