If the fluidity of the plastic is too large, or if too much lubricant is added, the pressure, speed, temperature, etc. should be properly reduced to reduce the amount of lubricant used. If necessary, a plastic with low fluidity should be used. 1.processing, adjustment: a.The set temperature, pressur... read more
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
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
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
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
