Mold temperature too low Cause: The low mold temperature causes the molten plastic to cool too quickly in the runner, preventing full fusion. Solution: Increase the mold temperature to ensure the molten plastic flows smoothly and fuses completely. Injection speed too slow Cause: Slow injection speed causes the plastic to flow slowly, extending cooling time and forming weld lines. Solution: Increas...

In the design process of composite materials, a series of important factors must be considered to ensure the performance, safety, and cost-effectiveness of the final product. These factors include material selection, structural design, manufacturing processes, environmental impact, and cost analysis. This article will discuss these key factors in detail and explain their importance in the design o...

In injection molding design, in addition to general mold design considerations, the following aspects should be given special attention: 1. To achieve the desired product dimensional tolerance, appropriate mold dimensional tolerances must be considered. 2. Preventing fluctuations in molding shrinkage rates should be accounted for. 3. Preventing molding deformation must be addressed. 4. Avoiding de...

1. Production Workshop The layout of the production workshop should consider two main aspects: meeting production requirements and optimizing layout based on production flow, while ensuring flexible energy use under specific production conditions. (1) Power Supply: Ensure a stable power supply with a moderate buffer to avoid excessive energy waste from unused capacity. (2) Efficient Cooling Water ...

Injection Mold 1. If the mold cavity is poorly machined, with defects such as scratches, micro-pores, wear, or rough surfaces, it will affect the gloss of the plastic part. To address this, ensure precise machining of the mold to achieve a lower surface roughness for the cavity; if necessary, polish and chrome-plate the cavity. 2. If the cavity surface has oil stains, watermarks, or excessive mold...
