Plastic injection molding wholesale provider today

Premium plastic injection molding manufacturer: 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.

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 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.

Sheet metal prototype mainly relies on sheet metal bending and other manufacturing processes to apply V-shaped and U-shaped pressure to metal sheets to create three-dimensional product prototypes, and cut, emboss, and link through processes such as laser cutting, sheet metal stamping, and metal welding. It can meet the needs of various industries such as shells, brackets, cabinets, boxes and other products. Relying on the characteristics of fast turnover and low cost efficiency, it is widely used in: medical, automobile manufacturing, aerospace, military, household hardware and other industries.

Rigid plastic overmolding process: After the internal base material is made of rigid plastic injection molding, another type of steel plastic is wrapped around the base material through an overmolding mold. The color of the material can be customized, but the material compatibility limit should be consulted. Otherwise, cavities or cracks will occur. Rubber overmolding plastic: The internal base material is made of steel plastic. After molding, the rubber material or TPE material is wrapped on the surface of the base material. The product presents the softness of rubber and can play a role in wear resistance and non-slip, such as: toothbrush handles, electric tool handles, etc. Find more information on https://www.china-plasticparts.com/.

Rotomolding products & mold design: We provide customers with professional rotomolding design technical support services, mainly focusing on the design of rotomolding molds. We use our rich experience to reduce quality risks in the design and ensure the high quality of products as you expect , And reduce the cost of mold modification due to design errors. In-house Mold Manufacturing: We have a powerful rotational molding mold manufacturing center, three 5-meter-long CNC machining centers, which can accurately engrave the details of the mold. Usually we will use high-quality aluminum alloy or cast aluminum to make rotomolding molds. High-quality mold manufacturing ensures that you can receive the highest quality products in the shortest time and have economic benefits. And we can add custom textures, logos, batch numbers and other copywriting on the surface of the mold.

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.
