Quality Control in Precision Injection Molding

introduction

Precision injection molding is one of the important processes for manufacturing high-precision and high-complexity parts, but some quality problems often occur during the manufacturing process, such as inconsistent dimensions, rough surfaces, and burrs. Therefore, in precision injection molding, quality control is of paramount importance. This article will discuss in detail the role of quality control in precision injection molding and introduce the advantages of JS Precision in this regard.

  1. Definition and application scenarios of precision injection molding

Precision injection molding is a process of injecting molten plastic into a mold to make parts. It can produce high-precision and high-complexity parts, which are widely used in electronics, medical equipment, automobiles, aerospace, and other fields.

  1. The importance of quality control in precision injection molding

In precision injection molding, quality control is the key to ensuring product quality. By mastering the quality control of injection molding machines, molds, raw materials, and quality control measures in the manufacturing process, production efficiency, and product quality can be effectively improved.

  1. Quality control of injection molding machines, molds, and raw materials
  2. Injection molding machine: The quality of the injection molding machine directly affects the size and surface quality of the parts. Therefore, when choosing an injection molding machine, the accuracy, stability, and repeatability of the machine need to be considered.
  3. Mold: The quality of the mold has a crucial influence on the size and surface quality of the molded part. Therefore, when making a mold, it is necessary to consider the selection of materials, processing technology, and dimensional accuracy.
  4. Raw materials: The quality of raw materials has an important influence on the physical properties and mechanical properties of molded parts. Therefore, when selecting raw materials, it is necessary to consider the composition, performance, and quality stability of the material.
  5. Quality control measures in the process
  6. Maintain the stability and repeatability of the injection molding machine, and achieve the best molding effect by adjusting the parameters of the injection molding machine.
  7. Maintain and clean the mold regularly to ensure the accuracy and stability of the mold.
  8. Precisely control the temperature, pressure, and flow of raw materials to ensure the quality stability of raw materials.
  9. Control the time and speed of injection molding to ensure the stability of product size and surface quality.
  10. Common injection molding defects and their causes
  11. Burrs: Caused by uneven mold, incorrect parameters of the injection molding machine, excessive raw materials, etc.
  12. Warpage: caused by uneven raw material temperature, uneven mold temperature, incorrect parameters of the injection molding machine, etc.
  13. Bubbles: caused by gas in the raw materials, incorrect parameters of the injection molding machine, etc.
  14. Application of detection technology in quality control

In precision injection molding, detection technology is one of the important means to ensure product quality. Commonly used inspection techniques include dimensional measurement, visual inspection, material analysis, etc.

  1. Methods and Practice of quality improvement
  2. Improve production efficiency and product quality through continuous improvement of processes and technology.
  3. Improve the technical level and quality awareness of employees through continuous training and technical exchanges.
  4. Through customer feedback and market research, understand market demand and improve the market competitiveness of products.
  5. Advantages of JS Precision in quality control
