Machine for production PET preforms XTREME | SIPA

XTREME is a rotary platform for manufacturing preform at high productivity and efficiency. With this revolutionary injection-compression molding system, SIPA has taken PET preform production into a new dimension. XTREME permits the highest L/t ratios in the industry, enabling you to produce preforms that are 8% lighter than even the lightest preform produced by conventional injection molding.

Using Hydraulics in Injection Moulding Machines | RG Group

Adjusting and monitoring hydraulic pressure controls the mechanical pressure. The mechanism for the screw which is moved by the hydraulic motor, coupled with the cylinder that propels the screw forward, make up a complex mechanism that require exacting hydraulic seals during the injection and packing process of the mold.

Injection Molding Hydraulics - The Pressure is Rising

The basic operation involved two halves of a mold, mounted on supporting platens, being clamped together at high pressure using hydraulic cylinders. Plastic substrate pellets were melted in a special screw device and the liquid injected under pressure into the mold cavity as fast as possible.

Direct Injection Logic: How The High-Pressure Fuel Pump ...

With the injector in the combustion chamber, the pintle and seat of the fuel injector are under extreme pressures. To overcome the cylinder pressures, the fuel pressure supplier to the injector may be as high as 2,000 psi. The in-tank pump in GDI systems is more responsible for volume than pressure.

Injection Molding Hydraulics - The Pressure is Rising

Injection molding technology, by comparison, is relatively new. The creation of celluloid by John Wesley Hyatt around 1900, heralded the new age of thermoplastics. These novel materials were moldable with the application of heat and pressure, but held their …

Cylinder-Pressure Based Injector Calibration for Diesel ...

For injection of the diesel fuel into the combustion chamber there are two main techniques, direct-injection and indirect-injection. In the direct-injection method, fuel is injected directly into the cylinder, where it is mixed with air. For a indirect-injection, the engine has an auxiliary injection combustion chamber where the fuel is mixed ...

Direct Injection Logic: How The High-Pressure Fuel Pump ...

A direct injection fuel pump can't increase its speed independent of the engine to increase it's output or pressure, so it has to control the volume of fuel that is compressed. This relationship is what makes direct injection high-pressure fuel pumps a mystery to some technicians and even engineers. But once you understand the relationship between the pump and control solenoid, your diagnostic ...

Injection Molding - an overview | ScienceDirect Topics

Clive Maier, Teresa Calafut, in Polypropylene, 1998. 14.2.3 Power systems. Injection molding machines perform a wide range of mechanical movements with differing characteristics. Mold opening is a low-force high-speed movement, and mold closing a high-force low-speed movement. Plasticizing involves high torque and low rotational speed, while injection requires high force and medium speed.

Pressure Loss Analysis In Injection Molding | The Tool Hub

When using a Scientific Molding procedure, parts are filled to around 95% in the first injection stage (Just short). When the part is short we know the plastic pressure at the end of flow is zero. To find the plastic pressure in each stage, we need to multiply the pressure at the transfer point (psi) × the intensification ratio of the machine.

Fuel Pump Pressure & Volume Testing | MOTOR

A healthy pump may manage to jump from 60 to 90 psi. But if the pressure rise is minimal, either the fuel pump is weak or something is keeping it from delivering its all. To prevent fuel percolation and aid hot- and cold-engine starting, fuel injection systems must maintain residual, or "rest," pressure when the engine …
