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.
We have successfully manufactured more than 8000+ high-quality molds and delivered them to buyers in 20+ countries around the world, and have been in stable operation for many years. As a custom mould manufacturer, We will make a rapid prototype for you, which will help you analyze and review your product design, and help you improve and adjust the product design to conform to the actual manufacturing process. When the product is in the mold, it is relatively soft at high temperature, and the unreasonable ejection method will leave a mark on the surface of the product. This problem is irreversible, but the defect can be compensated by hiding and reducing the cross-section of the ejector pin. Mulan Group Very good at solving such problems.
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.
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. Read more information at https://www.china-plasticparts.com/.
Place the thermoset plastic material in the compression molds cavity, melt the thermoset material by heating, close the mold with pressure, and the melted thermoset material will instantly fill the entire cavity under the action of pressure. In this process, it is very important to control the weight, shape, and specifications of solid materials, which will directly affect product quality. Thermosetting materials will reach the best curing state under the control of stable high pressure and high temperature. Compression molding parts are ejected, and the remaining materials are cleaned manually or by using cutting molds.
