Any product has its own defects, Shenzhen latex tube products is no exception,mainly manifested in the lack of rubber products; rubber edge is too thick, the product is overweight; curling, pumping edge shrinkage edge; crack; bubble; amolding products too rough to tear.
So, the causes of product defects in these Shenzhen latex tube which and the solution. Below small make up one one of the instructions.
1 reasons Shenzhen latex tube products lack of glue mainly has: the semi-finished product unit consumption inadequate or insufficient amount of loaded adhesive; glue plate rise too fast, not fully flow; mould seal glue; mold ventingcondition is poor; mold temperature is too high. Can be solved from these aspects: from the new determination of mould installed glue quantity; slow down the plate rise velocity and repeatedly deflated; improve the mold design; reduce the die temperature, speed operation; reduce the die temperature.
Glue edge too thick 2 Shenzhen latex tube, the reason mainly has: productoverweight loading rubber is too large; flat pressure is insufficient; die withoutresidual glue groove corresponding. Can be solved from these aspects: strict control of semi finished products consumption; increase the flat pressure;improve the mold design.
3 Shenzhen latex pipe crimping, pumping edge shrinkage edge reason mainly has: rubber processing performance is poor. Can be solved from these aspects: using the Mooney viscosity of casting pressure, injection production decrease rubber.
4 Shenzhen latex pipe crack reason mainly has: Rubber dirt; isolating agent is excessive; scorch. Can be solved from these aspects: to ensure the half finishedcleaning; rational use of isolation agent; prolong scorch time.
5 reasons Shenzhen latex tube bubble mainly has: the material processing technology with the agent containing sulfide gas decomposition of the die cavityof the air pocket, not completely exhaust; mould without exhaust line. Can be solved from these aspects: the mold closing repeatedly before discharging, dieadditional exhaust line; calcium oxide is added in the formula
6 Shenzhen latex tube reason mainly has: mold tear isolation agent too much or too little; opening mould too fast and uneven stress; rubber poor mobility, semi-finished adhesive difference; die corners, chamfer is not reasonable. Can be solved from these aspects: the reasonable use of isolating agent, opening mouldproduct has uniform stress and viscosity reducing gate sizing material, improve the mold design.
7 Shenzhen latex tube reason mainly has: the product is too rough mouldsurface roughness; rubber scorch time too short. Can be solved from these aspects: the cleaning mold; prolong scorch time.
In short, Shenzhen latex tube product defects and the causes of defects and thesolutions are in the top one one lists, and they hope to help everyone.
