Blow mold factory in China

Blow molding wholesale provider right now: Stretch blow molding is the process method of billet, stretch and blow molding in a machine. Billet is a semi-finished product in the production process. After cooling, cold billet is reheated to stretch and blow molding. After extrusion molding, directional tensile blow molding, maintain a certain tensile speed, orientation before blowing, after stretching, transparency, impact strength, hardness and rigidity, surface gloss and barrier properties have been higher. The production process of stretch blow molding is to control the temperature of the billet below the melting point under the principle of bidirectional bigeneration to improve the strength of the product.

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.

Blow molding is a process in which a hollow product formed by the expansion of a hot-melt plastic tube closed in a mold by means of gas pressure. The blow molding process was used to produce LDPE vials in World War II. In the 1950s, with the birth of HDPE materials and the development of blow molding machines, the blow molding process was widely used and the technology was upgraded. According to the different plastic blank tubes, it can be divided into extrusion blow molding, injection blow molding, stretch blow molding and multi-layer blow molding. Compression molding process A manufacturing process for molding polymers such as thermosetting plastics, thermoplastics, elastomers, rubber and plastic materials, and natural rubber. For example: children’s pacifiers, sealing rubber rings, power insulation parts, electrical enclosures, etc.

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.

Plastic overmolding metal: We use CNC machining/metal casting/sheet metal bending/sheet metal stamping on metal materials to pre-mold the designed substrate, and then wrap the plastic around the metal substrate at one time through overmolding, such as: pipe connectors , Electronic components, etc. Rubber overmolding metal: We use CNC machining/metal casting/sheet metal bending/sheet metal stamping on metal materials to pre-mold the designed substrate, and then wrap the rubber material on the surface of the metal substrate through overmolding to present a soft rubber layer. Such as fitness equipment, medical supplies, hammer handles, children’s toys, etc. Find even more info on https://www.china-plasticparts.com/.

We have 6 large-scale automated CNC rotational molding equipment, 7*24 hours for production tasks, to ensure that all products can be delivered to customers on time, and our production plan is not limited by the number, at least one piece can start our production plan. In order to better customize the rotomolding parts according to the customer’s design, we will perform secondary processing on the finished product to ensure the realization of the functional application of the product. like: In-mold inlay: Fix metal fasteners or other metal parts in the mold, used for fastener assembly between products, metal reinforcement ribs and other functions.

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.
