The injection molding production process of nylon handheld frame mainly includes the following steps:
1. Raw material preparation: First of all, we need to prepare the raw materials suitable for making nylon handholder, usually nylon particles. According to the needs of the product to choose different types and characteristics of nylon materials.
2. Drying treatment: Since nylon material is easy to absorb moisture, it is necessary to dry the raw material before injection molding to reduce the moisture content and avoid bubbles or affect product quality during injection molding.
3. Mold design and manufacturing: design and manufacture the corresponding injection mold according to the design drawing of nylon holder. The quality of the mold directly affects the appearance and performance of the final product, so this step is very important.
4. Preheating the mold: heating the mold to the appropriate temperature helps to improve the material fluidity, make the filling more uniform, and reduce the cooling time.
5. Injection molding: the dried nylon particles are sent into the injection molding machine through the hopper, melted into liquid under high temperature and high pressure, and then injected into the pre-prepared mold. This process needs to control the temperature, pressure, injection speed and other parameters to ensure product quality.
6. Cooling and curing: the liquid nylon injected into the mold will gradually cool and cure to form. The cooling time and method will also affect the quality of the product, such as surface finish.
7. Demoulding and taking out: After the nylon is completely cured, open the mold and take out the finished product. Sometimes it may be necessary to use a thimble or other auxiliary tool to help with demoulding.
8 Finishing processing: for some complex shape products, may also need to go through grinding, cutting and other subsequent processing steps to achieve the final requirements.
9. Quality inspection: Finally, carry out a comprehensive quality inspection on the production of nylon holder, including dimensional accuracy, strength test, appearance defect detection, etc., to ensure that the standard can be sold before delivery.
Nylon products are also used in automotive, daily commodity and electronic components. Nylon material has better thermal properties, high temperature resistance and corrosion resistance.
In the whole production process, it should be noted that in order to obtain high-quality products, each step needs to be operated in strict accordance with the process requirements, and the production equipment should be maintained regularly to ensure that it is in good condition
