    How to overcome the defects of injection moulds

    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 mo... read more

    How to properly reproduce the texture of the mould surface

    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 coo... read more

    Most injection moulds are made from cooling channels

    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 h... read more

    Injection machines can be used to produce various thin walled products

    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... read more

    The advantages of thin wall injection moulding

    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. %~... read more
