plastic precision injection mold
Today's precision molds refer to molding molds with complex structure and high-precision molding molds.
The mold with complicated structure and process needs to realize many functions on a small mold volume. For example, the automotive coupling needs to realize the encapsulation and secondary implantation of the plastic material of the metal terminal on the mold. Or the packaging bottle of the daily chemical product, on the basis of ensuring the consistency of the multi-cavity common mode, realize the actions of opening and closing the lid and twisting the teeth.
High-precision mold means that the size of the molded product changes little, the consistency is very high, the mold is often small, but the cost is high; it involves optical components, electrical equipment parts, consumer electronics industry, etc.
1. Pay more attention to appearance: such as consumer electronic products, mobile phones, mobile power supplies and other products, the surface type should not be rough, and there should be no obvious signs of material combination. Because of cost control, under the spray-free process, it may also require the realization of highlights or special textures.
2. More precise size control: mainly reflected in small-sized connectors, LED light controls, optical fiber heads and other precision components. This type of product requires the production of precision molds with extremely small tolerances, and also considers various variable factors in the design stage to match them to meet the needs.
3. More composite material manufacturing molds: such as mixed molding of multi-color materials, high-temperature reinforced composite modified materials, these require molds to be able to undertake long-term production tasks in high-temperature environments.
4. The product structure is complex, which requires the mold to make coherent actions in the structural design and can run the continuity of multiple actions. These include multiple row activities, core pulling, internal and external twisting teeth, and so on.
Until/with the development of business, the increase of factory investment, the development of more high-precision iterative products by equipment manufacturers, and the relaxation of export controls on China (there are still some devices that do not open export rights to China), factors such as hardware Update development is introduced quickly. The mold-making technology that was subject to Taiwan, Hong Kong and other places also passed from the master to the apprentice and flowed to the mainland, gradually improving in terms of process and craft. The software is also from the initial hand drawing, graphic design to today's 3D design. This process is influenced by many factors and acts on this industry, and only then produces more rich and exciting high-precision products.
