Injection mold wholesale factory 2024: 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. Read extra details on blow mold services.

In order to verify that our mold is correct, we will conduct multiple trial runs of the mold, each time not less than 50 samples are spot-checked, and the product changes at different temperatures and different cooling times will be tested. These samples will be in the truth. Send it to the buyer for verification, and a list of equipment parameters for product production will be attached as your production basis. Every buyer expects quick response, high-quality and low-cost manufacturing feedback, which is beneficial for commercial activities. But this is contradictory in the manufacturing industry. High-quality injection molds must choose high-cost materials, and after high-precision cnc machining, all steps must use the best labor and accessories, and all processes must comply with international standards. standard. In Mulan Group, we can achieve a quick response quotation process at any time, but after facing high-quality mold requirements, we can only send a reasonable quotation, and will not unreasonably lower the market price. It depends on what we will do for you To save technology development costs, we refuse to cut corners. But compared with the actual use value of molds.
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.
Rotomolding molds are usually made of cast aluminum or steel plates without the aid of high pressure, so the mold process is relatively simple, the cost is low, and small batch production has economic advantages and is suitable for early investment in product development. Rotomolding relies on the material to adhere to the inner wall of the mold, which has very low restrictions on the shape of the product. It can be achieved smoothly through reasonable design of the mold details. And you can easily create functions such as reinforced ribs, custom textures, and in-mold inlays.
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 even more 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.
Compression molding also has the characteristics of high productivity, but it does not have the accuracy and consistency of precision injection molded parts. It can create durable simple parts at low cost. It is often used for high-volume but low-precision product needs. This plastic molding manufacturing process, which can be completed by heat and pressure, is one of the most popular and cost-effective manufacturing processes in the manufacturing of plastic products and components.
