Best blow mold manufacturer factory: 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.

With their ability to cater to diverse industries such as automotive, aerospace, medical devices, consumer electronics,and more – precision molds are indispensable assets in bringing innovation and excellence into the world of manufacturing. Compared with similar products on the market, precision mold has incomparable outstanding advantages in terms of performance, quality, appearance, etc., and enjoys a good reputation in the market. MULAN summarizes the defects of past products, and continuously improves them. The specifications of Precision mold can be customized according to your needs.
As an injection mold manufacturer, Mulan Group has been engaged in plastic molding molds for more than 25 years. We have a professional in-house mold manufacturing factory, located in Shanghai, China, a high-quality mold manufacturing base, equipped with a team of engineers with rich manufacturing experience and professional knowledge. Rely on digital programming software and equipment to customize precision injection mold services after the part design is completed. Allow the material to fill the mold cavity without obstacles to ensure that the product will not have defects. For some appearance parts, a smooth surface is an important factor in obtaining market value. We will use very small pinhole feeds. There are no traces on the surface of the product, and it is hidden on the surface of the product installation part.
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 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.
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. Read extra details at china-plasticparts.com.
Rotational molding has also become rotomoulding. It is a kind of manufacturing process that is very versatile and suitable for various industries. It can be customized to produce hollow plastic molding products of various shapes and sizes. No matter the batch is large or small, the volume is large or small, roto molding services Both can achieve multi-functional manufacturing functions. Professional rotomolding mold engineers will have great design freedom, because this is a plastic molding process that does not limit any shape and size, similar to casting technology.
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.
