Two-Color Needle Valve Copper Sleeve Medical Helmet Hot Runner Mold

Hot runner of copper
bush heater
• European heater and highly conductive
copper material can improve heat conductivity
and realize uniform temperature and stable
quality.
• It is heated using standard copper casting and
in stock and features fast delivery and easy
replacement.
• The position of the heater is fixed, so it can be
produced under normal temperature in spite of
adhesive leakage.SPECIFICATIONPart NameMedical helmetNumber of Cavities2+1 pcsPart Weight189 g + 11 g + 21 gGating on Part/RunnerPartWall Tickness0.5 mmNumber of Heaters9 pcsType of MaterialTPE+PCGate Dimensionsφ2.0+1.5 mmcolourblue+lucencyNozzle Runnerφ12.0 mmMaterial Color ChangeyesProcessing Temperature210+300ºC

Advantage of using hot runner

A.Simplified mold design, unlike the three plate mold has 2 to 3 parting surface, the material head is not easy to take and install automatic operation difficulties, the middle plate makes the guiding system wear quickly, the drive drive trouble, open and close mold time than the single parting surface long, the material head proportion (such as bottle cap mold).

B.Limited melt temperature drop, long enough flow into the cavity, good for the crystallized material with narrow temperature range, F7 die injection, no need to raise the injection temperature to compensate.

C.Precise temperature regulation for each gate.

D.Small pressure loss, make the high pressure melt into the cavity, reduce the injection pressure, clamping force, holding pressure longer, more effective.

E.More freedom to optimize the choice of gate, more uniform filling flow, less temperature and pressure loss and shrinkage difference, internal stress.

F.Glue can be added sequentially to adjust the bonding line and maintain pressure.

G.Make the lamination possible.

H.Save labor (cutting head, secondary processing, grinding, pumping).

I.Save time (period).

J.Save electricity, save material (available small machine, no crushing cycle, may CPI, PPI, 845 large power plant losses, electricity prices rose.Material price increases, recycled material is not easy to use, easy to change the characteristics)
