Plastic mold manufacturer today: Blow molding is widely used in the production of hollow structure products, such as: water bottles, oil drums, chemical turnover barrels, floats, medical reagent bottles, etc. Injection blow molding is suitable for small container production, and stretch blow molding is suitable for medium and large-volume container products. However, the surface effect of injection blow molded products is better than stretch blow molding, and can be highly transparent and flat. Drinking water bottles are the most typical injection blow molding. Blow molding has many limitations due to the molding principle, so there are a few points that should be paid attention to when designing blow molding products: Only limited to hollow structural parts. The wall thickness is thin and the strength is low. By adding other materials in the multilayer part, the effect of blocking sound and heat sources is increased. (So not recyclable) A second trimming is required to remove burrs and excess material. Find extra details on China plastic molding company.
Only high-quality molds can produce high-quality products. Many times we will receive feedback from customers, “I don’t agree with the price of your injection mold, why is it so high?”. Such problems are mainly concentrated in non-professional mold technicians, who only calculate the average cost of the mold on the product, without real research and exploration, how important a high-quality mold is to the quality of the product and the progress of the overall project. We have many methods for low-cost molds, but we have lost 100% of the assurance of the quality of your products. The cost of the mold depends on the size, structure, material, product quantity and other special requirements of the part. For example: if you need 1,000 injection parts, then we will actively recommend that you choose a low-cost single-cavity mold, which can meet the quality and deliver the product on time. The most important thing is low-cost investment.
In the production process, it is difficult to completely fill the mold, and there are certain technical requirements. After the curing stage is over, different products have different stiffness, which has an impact on product performance. For products with high dimensional accuracy requirements (especially for multi-cavity molds), the process is somewhat short. The flash of the final product is thicker, and the workload of removing the flash is large. The shortcomings of compression molding are that the mold manufacturing is complicated, the investment is relatively large, and coupled with the limitation of the press, it is most suitable for mass production of small and medium composite materials.
Sheet metal prototype is a method to quickly create design details of metal parts through manufacturing processes such as cutting, bending, stamping, and stretching of metal plates. In this process, it will try to use as little mold investment as possible. It is widely used in the development and research phase of metal products to help customers test product functionality and design rationality. More often, we rely on sheet metal prototype to provide metal inserts for the plastic molding process of in-mold molding, and the prototype can be produced within a few hours.
We can come into contact with toothbrushes every day. Its base material is injection molding made of steel plastic, which is very hard and tough. The rubber handle on the handle can effectively help us to prevent slippage, and can improve the color matching and aesthetic appearance. The product is derived from the overmolding process and is suitable for mass production. Improve product surface friction; Can achieve a more ergonomic design; Improve product electrical insulation; Create products with better sealing; Effectively isolate vibration and sound transmission. Improve color matching options and improve aesthetics. Reduce the use of harmful adhesives and other consumables. Increase manufacturing efficiency, suitable for mass production. The product structure is not restricted, and the adaptability is high. Discover many more info at https://www.china-plasticparts.com/.
The process of rotational molding is much simpler than the manufacturing process that relies on pressure molding, but in fact it requires very rich experience and technical knowledge. While the material cannot be controlled by high pressure, the environmental temperature, environmental humidity, mold type, material specification, material Factors such as pretreatment quality will directly affect the final quality of rotomolding products. Put the powdered plastic into the hollow mold. Close the mold and rotate along the two axes. Heating the mold during the rotation process to melt the powder material. After all the materials are melted, cool the mold.After the product has solidified, open the mold and take out the product.
