Custom compression wholesale factory 2025: Introduction to Blow Molding – Blow molding is a manufacturing process used to create hollow plastic parts, such as bottles, containers, and tanks. It works by inflating a heated plastic tube, called a parison, inside a mold until it takes the shape of the cavity. Once cooled, the plastic retains the mold’s shape and is ejected as a finished part. This process is especially valuable in producing lightweight, uniform, and durable items in large quantities. The technique originated from glass-blowing concepts but evolved with the advent of thermoplastics in the 20th century. Today, blow molding is widely used across industries including packaging, automotive, and consumer goods. Its key advantages are high production speed, low material waste, and design flexibility. As environmental concerns grow, manufacturers are increasingly exploring recyclable and bio-based plastics, ensuring that blow molding continues to adapt to sustainability trends while meeting industrial demands.

Applications of Compression Molding – Compression molding is widely used across industries due to its versatility and ability to produce durable, high-strength parts. In the automotive sector, it’s used for manufacturing bumpers, fenders, and structural panels made from glass-mat thermoplastics (GMT) and sheet molding compounds (SMC). The aerospace industry employs compression molding for producing lightweight composite components like interior panels and structural supports. Electrical and electronic applications include insulating parts such as circuit breakers, switch housings, and connectors made from thermoset materials. Consumer goods, sports equipment, and household appliances also benefit from the process, particularly for ergonomic, heat-resistant parts. Its ability to form complex shapes in a single step makes it cost-effective for medium- to high-volume production. As sustainability becomes more important, compression molding is increasingly used for eco-friendly materials like bio-resins and natural fiber composites, aligning performance with environmental responsibility.

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.

We have 6 large-scale automated CNC rotational molding equipment, 7*24 hours for production tasks, to ensure that all products can be delivered to customers on time, and our production plan is not limited by the number, at least one piece can start our production plan. In order to better customize the rotomolding parts according to the customer’s design, we will perform secondary processing on the finished product to ensure the realization of the functional application of the product. like: In-mold inlay: Fix metal fasteners or other metal parts in the mold, used for fastener assembly between products, metal reinforcement ribs and other functions.

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 a lot more details at https://www.china-plasticparts.com/.

In the production process, it is difficult to completely fill the mold, and there are certain technical requirements. After the curing stage is over, different products have different stiffness, which has an impact on product performance. For products with high dimensional accuracy requirements (especially for multi-cavity molds), the process is somewhat short. The flash of the final product is thicker, and the workload of removing the flash is large. The shortcomings of compression molding are that the mold manufacturing is complicated, the investment is relatively large, and coupled with the limitation of the press, it is most suitable for mass production of small and medium composite materials.

Rich production experience allows Mulan Group’s services to meet the products of various industries. Mulan Group has participated in many important product development and manufacturing to understand the use characteristics and requirements of different products. In other words, only a brief description of the customer, the production plan and the actual cost of the product can form a formal report.
