Horizontal injection molding machine It is the key equipment for manufacturing plastic products, so it is very important to ensure product quality in the production process. Product quality control and quality inspection are important steps to ensure that products meet specifications and standards. This paper will discuss the product quality control and quality inspection methods of horizontal injection molding machine.

1. Quality control of raw materials:

One of the primary factors of product quality is the quality of raw materials. Before injection molding production, strict quality control must be carried out for plastic particles. This includes checking the composition, color, size and humidity of the particles. Only raw materials that meet the specifications can be used in the injection molding process.

2. Temperature and pressure control:

In the injection process of horizontal injection molding machine, the control of temperature and pressure is very important. By ensuring that the temperature and pressure of the molten plastic are within the appropriate range, product defects such as warpage, bubbles and deformation can be avoided.

3. Injection speed control:

Injection speed is another key factor affecting product quality. Too fast or too slow injection speed may cause product quality problems. The control system of the horizontal injection molding machine allows the operator to precisely control the injection speed, so as to ensure that the product can fully fill the mold and achieve consistent quality.

4. Mold design and maintenance:

The design and maintenance of mould is very important to product quality. The mold design must consider the product geometry, wall thickness, cooling and exhaust system. Regular mold maintenance can ensure that the mold is kept in the best working condition and avoid product defects.

5. Quality inspection tools and equipment:

The product quality control of horizontal injection molding machine cannot be separated from quality inspection tools and equipment. These tools include thickness gauge, dimension measuring tool, quality image scanner, X-ray testing equipment, etc. These tools help operators to check the size, shape, surface quality and internal defects of products.

6. Sampling inspection:

Sampling inspection is a commonly used quality control method. The quality of the whole batch can be evaluated by randomly selecting some products from the production batch and testing them. If the sampled products meet the specifications, the whole batch can be considered to meet the requirements.

7. Traceability and records:

In order to track product quality and troubleshoot problems, manufacturers of horizontal injection molding machines usually establish traceability systems. This includes recording the details of each production batch, such as raw material batch, production time, operator and quality test results.

8. Continuous improvement:

Continuous improvement is the key to ensure product quality. By monitoring problems in the production process, collecting feedback and regularly reviewing quality control methods, manufacturers can continuously improve production processes to improve product quality.

Lian Sheng Injection molding machine manufacturer To sum up, the product quality control and quality inspection of horizontal injection molding machine is the key link in the manufacturing process. By strictly controlling the quality of raw materials, injection parameters, mold design and maintenance, and with the help of quality inspection tools and sampling inspection, products can be ensured to meet the specifications and customer needs. The method of continuous improvement helps to continuously improve product quality, improve manufacturing efficiency, reduce scrap rate and enhance enterprise competitiveness.
