Custom Injection Molding Molding Process Control - Measurement

Two component liquid is generally MASTER chair mould by the hydraulic system to complete hydraulic system consists of pumps, valves and accessories (control liquid materials distribution pipeline system and control the work of the cylinder oil system) formed. After injection need MASTER injection mould design voltage switching means to the injection pressure is converted to the desired pressure. Hydraulic pump liquid quantitatively measured output, requiring measurement accuracy of at least ± 1.5%, the best control in ± 1%.

The new reaction injection moulding

The utility model relates to a plastic polyurethane reaction injection molding industry. The A, B tank, metering pump, and the injection head and the conveying conduit is disposed MASTER wheel covers molding the mold holder constituting the injection head, the A, B disposed above the feed tank and metering pump are encapsulated together with the conveying line a heater casing with insulation, the insulation housing is MASTER injection mold maker in the mold base. reaction injection moulding small timber with low power consumption, manufacturing cost is low, and the injection of more reliable quality advantages. Can replace the existing layout style polyurethane reaction injection molding.

Variable fiber reaction injection moulding

reaction injection moulding technology is the first fiber MASTER plastic pallet mould in the mold cavity, and then injected into the liquid resin. The disadvantage is the need to pre-process the fiber mat, so that the process becomes complicated and increases the cost. In addition, as laying MASTER custom plastic mold felt the need to manually perform, but also greatly increased the labor intensity. Based on this, but also spawned a variable fiber reaction injection molding.

plastic injection toy mould tram shell design

Determine the product materials 

Because plastic injection toy tram shell comprehensive performance mould good, as MASTER rattan sofa mold impact strength, dimensional stability, ease of molding, heat and MASTER mould information resistance and good resistance to cold, in the -40 ℃ low temperature is still a certain mechanical strength. Determine material: tram shell.

plastic injection toy mould car cavity molds to determine the number of

Determining the number of mold cavity
Common method to determine the number of mold cavity injection mold toys are:
(1) determine the MASTER plastic pallet mould of cavities in accordance economy;
(2) determine the number of cavities in accordance with clamping force;
(3) determine the number of MASTER egg tray mold based on the accuracy of the cavity;
(4) determine the maximum injection volume based on the number of cavities.
To ensure the mold compact and economy, to determine the number of mold cavities.

Introduction plastic injection toy mould car double injection mold parting surface

Introduce double injection mold parting surface: it single injection mold parting surface compared to the addition of a gating system for taking parting slug. Thus, called dual injection mold MASTER plastic injection mold makers surface. Double injection mold parting surface can be located in the center of the product Ge point gate area, but high cost, MASTER plastic mold manufacturer structure, requires a larger opening stroke, it is less for large injection molded plastic products.
After analysis, using a single injection mold parting surface toy structure. Because toy tram shell surface should be smooth and beautiful, so rectangular side gate.

Mold Introduction
Injection mold structure in the form of toys, plastic mold is determined to ensure that the main tool for plastic shape, size, precision and surface quality, is one of the MASTER mold elements of the molding process. By injection molding can be divided into general structural features: dual injection mold parting surface and a single injection mold parting surface,
Single injection mold parting surface of introduction: Since only one parting surface, it is called a single injection mold parting surface, also called two-plate injection molding. This injection mold with a simple structure, and the most. After clamping, move, scheduled to die combination constitutes cavity side of the MASTER pvc pipe fitting mould mold sprue, runner and gate agency has launched on the parting, moving mold for plastic parts and casting system introduced slug . Simple single injection mold parting surface structure, convenient operation, but in addition to using direct gate outside the cavity gate bit Ge can choose the side of the product to release from the parting line.
