Injection Moulding Machine & Components of Injection Moulding Machine

The injection molding machine converts granular or pelleted raw plastic into final molded parts via a melt, inject, pack and cool cycle.

Components of Injection Moulding Machine

A typical injection molding machine consists of the following major components,

Injection system

Hydraulic system

Mold system

Clamping system

Cooling System

Control system

Injection System

The injection system consists of a hopper, a reciprocating screw and barrel assembly and an injection nozzle. This system confines and transports the plastic as it progresses through the feeding, compressing, degassing, melting, injection and packing stages.

Hydraulic System

The hydraulic system on the injection molding machine provides the power to open and close the mold, build and hold the clamping tonnage, turn the reciprocating screw, drive the reciprocating screw and energize ejector pins and moving mold cores. A number of hydraulic components are required to provide this power, which includes pumps, valves, hydraulic motors, hydraulic fittings, hydraulic tubing, and hydraulic reservoirs.

Mould system

The mold system consists of tie bars, stationary and moving platens as well as molding plates (bases) that house the cavity, sprue and runner systems, ejector pins, and cooling channels. The mold is essentially a heat exchanger in which the molten thermoplastic solidifies to the desired shape and dimensional details defined by the cavity.

Clamping System

The clamping system opens and closes the mold, supports and carries the constituent parts of the mold and generates sufficient force to prevent the mold from opening. Clamping force can be generated by a mechanical (toggle) lock, hydraulic lock or a combination of the two basic types.

Cooling System

Cooling time is by far the most dominate time consumer in the injection molding cycle. A long cycle time means that the molder must charge more for the same part. During Product Design we should use thermal analysis capabilities to specify the cooling design for the tools. The result will be a low cost tool that will run fast and keep your cost per part as low as possible.

Control System

The control system provides consistency and repeatability in machine operation. It monitors and controls the processing parameters including the temperature, pressure, injection speed, screw speed, position and hydraulic position. The process control has a direct impact on the final part quality and the economics of the process.

306 d'turbo engine change HELP?

Hi, i have a peugeot 306 d'turbo 1996 and its running with a lucas diesel pump, the car needs a new engine and was thinking of buying a engine with a Bosch pump, would this be a straight swap of the engine or would it not work because the pump change i the engine? or would there be extra work to do to get it to fit? the car is a Indirect Injection XUD engine.
regards gary

No problem - the engine & pump will drop straight in, regardless of the pump maker.
