Custom compression wholesale manufacturer right now: 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.

The Compression Molding Process Step-by-Step – The compression molding process begins with preparing a measured charge of raw material—often in the form of pellets, powder, or preform. This material is preheated to enhance flow before being placed into the lower half of a heated mold cavity. The mold is then closed, and pressure is applied using a hydraulic press. Heat and pressure cause the material to soften and conform to the mold’s contours, filling every cavity and eliminating voids. For thermosetting materials, the heat initiates a chemical crosslinking reaction, permanently hardening the part. Once curing is complete, the mold is opened, and the finished part is ejected. The process may include post-curing or trimming to achieve final specifications. This straightforward yet precise sequence ensures high-quality molded components, with cycle times ranging from a few minutes to over an hour, depending on material type and part complexity.
Choosing high-strength mold steel to manufacture the main body of the mold can obtain perfect precision and details from the precision CNC Machining process, and effectively extend the service life of the mold.

Blow molding is a plastic molding process for rapid production of hollow structure products. Many products in life will choose injection blow molding for packaging, such as water bottles, oil drums, children’s toys, etc. This is an economical and efficient plastic molding process. It is also suitable for mass production of plastic products. Mulan Group has been engaged in the production of blow molding parts for more than 15 years. It has two large blow molding manufacturing bases that produce small injection blow molding parts, such as medical test tubes, cosmetic bottles, drinking water bottles, etc. And large-scale extrusion blow molding products, such as insulation barrels, oil drums, car water tanks, tool boxes, etc.
Common rotomolding products include: water storage tanks, oil storage tanks, large buckets, kayaks, fitness equipment, trash cans, mobile toilets, traffic barriers, cartoon dolls, septic tanks, etc. Mulan Group has been focusing on helping customers develop, design and manufacture a series of customized rotational molding services, with rich experience and expertise. In 2014, we established a large rotomolding factory and established an advanced manufacturing system with 6 large-scale rotational molding parts. The automated rotational molding equipment has a maximum rotation capacity of more than 10 feet. We actively respond to all complex rotational molding projects at any time, constantly challenge opportunities and raise technical barriers.
Overmolding process is a unique injection molding process. After injection molding the internal base material (usually metal and plastic materials with higher hardness), it is placed in overmolding molds for molding and cooling. When the injection molding parts you need to take into account the characteristics of sturdiness, practicality, beauty, etc., you must consider using injection overmolding. This is an efficient and cost-effective molding process, suitable for multifunctional injection molding solutions in all walks of life. See extra details at https://www.china-plasticparts.com/.
Mainly used as structural parts, connectors, protective parts and electrical insulation parts. It is widely used in industry, agriculture, transportation, electrical, chemical, construction, machinery and other fields. Because of the reliable quality of molded products, they have also been used in weapons, aircraft, missiles, and satellites. The molding cycle in the entire production process is long, the efficiency is low, and the staff has a large physical consumption. It is not suitable for molding complex products with depressions, side slopes or small holes.
