Quality plastic injection molding company supplier
Plastic injection molding factory today: Film blow molding: the molten plastic is extruded from the circular gap of the extruder head mouth die in a cylindrical thin tube, while the compressed air is blown into the thin tube cavity from the center hole of the head, the thin tube is blown into a larger diameter tubular film, and then rolled up after cooling. Hollow blow molding: With the help of gas pressure, the rubber type blank closed in the mold cavity is blown into a secondary molding technology of hollow products, is the production of hollow plastic products. The manufacturing methods of hollow blow molding are different, including extrusion blow molding, injection blow molding and stretch blow molding. Discover more info at blow molding services.
Mulan Group currently owns 2 manufacturing companies and holds 3 processing plants. Its business scope includes: CNC Machining Service, Sheet metal Fabrication, Rapid Prototyping, Plastic injection molding service, mould tools, etc. An experienced team of engineers and an efficient sales team provide quick feedback to all production project queries for global buyers. According to the different application requirements of the product, we can take several different ways to carry out plastic overmolding, the main difference is the combination of different materials.
Our team of mold experts will write precision machining programs according to the design of the product, and have a very efficient and fast response. All accessories are provided by excellent suppliers, and the material report and physical performance report can transparently confirm that the mold has high-quality manufacturing capabilities. Reliable DFM is the key to our project. Because all processes are completed under our supervision, the DMF report is very credible and reliable. Relying on the uninterrupted sampling and testing by quality inspectors, the results of the first batch of samples will be quickly obtained, and the change trajectory of the product under different parameters will be recorded in detail. In order to inform you of the actual operation manual. Finally, we will send you all the test samples, and you will understand our test content, because you believe in Mulan Group, so you need to understand these processes more than we do.
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. Discover a lot 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.
The shrinkage of the product is small and the repeatability is good. A mold with a large number of cavities can be placed on a given template, and the productivity is high. It can be adapted to automatic feeding and automatic removal of products. High production efficiency, easy to realize specialized and automated production. The product has high dimensional accuracy and good repeatability. The surface is smooth and clean without secondary modification. Products with complex structures can be formed at one time. Mass production, relatively low price.
