Defects visible on the surface of injection moulded articles include dark spots, gloss differences, or fogging areas, and surface wrinkling or what is known as orange peel. Usually these defects occur near the gate or behind the sharp corners of the gate area. Starting from the two aspects of the mould and the moulding process, […]

In this modern era where production processes have become complex and varied, Auto Moulds have become a necessary part of the process. Auto Part Mould companies provide a range of services to meet the diverse requirements of manufacturing industries dealing in almost all types of vehicle parts. These Auto Mould companies have experienced Auto Part Mould designers

Dark spots not only occur at the gate, but also often appear after the sharp corners of the article are formed. For example, sharp corner surfaces of articles are generally very smooth, but very gray and rough behind it. This is also due to the excessive flow rate and injection speed causing the cooling surface

When using plastic injection moulding (PIM), it is important to control heat. Most injection moulds are made from cooling channels that are drilled or milled from a steel block. Cold water flows through these channels to cool the core and draw heat away from the plastic. Traditionally, these paths have been made by drilling straight

The demand for small and light parts has made thin-wall injection moulding the most demanding performance of injection moulding machines. “Thin wall” is usually defined by lightweight electronic parts with a wall thickness of less than 1 mm. For large automotive parts, the “thin wall” can be 2mm. In summary, thin-walled products require changes in

As for the injection volume, the large diameter barrel is often too large. The recommended injection volume is 40% to 70% of the barrel capacity. The total moulding cycle of thin-walled products is greatly shortened, and it is possible to reduce the minimum injection volume to 20 barrel capacity. %~30%. The user must be very

As the plastic flows through the injection moulding machine and the different parts of the mould, the pressure acting on the leading edge of the plastic flow is lost due to the effects of drag and friction. In addition, as the plastic contacts the mould wall, it begins to cool, increasing the viscosity of the

The melt usually flows from the nozzle into the nozzle, but with some moulds, the nozzle is part of the mould because it extends to the bottom of the mould. There are two main types of nozzles: open shot nozzles and closed nozzles. In injection moulding, open nozzles should be used more because they are

Some plastics need to be vented in the shooting tank during injection moulding to allow the gas to escape. In most cases these gases are only air, but they may be melted moisture or monomolecular gases. If these gases are not released, the gas will be compressed by the melt and brought into the mould,

Bathtub Moulding is a service that is required to give a beautiful look to your bath. However, this process needs to be done by professional since it can be a complicated job for an amateur. There are two different types of this service. The first type of is where you will be the one doing the
