High quality blow moulding manufacturer: Types of Blow Molding Processes – Blow molding encompasses three main types: extrusion blow molding (EBM), injection blow molding (IBM), and injection stretch blow molding (ISBM). In extrusion blow molding , molten plastic is extruded into a parison and then inflated inside a mold — ideal for making bottles, containers, and large industrial parts. Injection blow molding combines injection and blow molding by forming a preform first, then blowing it into shape; this yields precise, uniform parts commonly used in pharmaceuticals and cosmetics. Injection stretch blow molding adds a stretching step before blowing, improving strength and clarity — perfect for producing PET beverage bottles. Each method offers distinct advantages depending on production volume, material, and desired product characteristics. Choosing the right blow molding process involves balancing cost, speed, and performance requirements, making process selection a crucial part of manufacturing design.
Introduction to Compression Molding – Compression molding is a manufacturing process used to shape thermosetting plastics, thermoplastics, and composite materials. It involves placing a preheated polymer charge into a heated mold cavity, then applying pressure until the material conforms to the shape of the mold. The heat and pressure cause the material to flow and cure, forming a rigid part once cooled. This method is especially popular for producing durable, high-strength components like automotive parts, electrical housings, and appliance panels. Compression molding stands out for its cost-effectiveness, material efficiency, and ability to produce large, intricate parts with excellent dimensional stability. Compared to injection molding, it typically requires simpler equipment and tooling, making it suitable for medium to high production volumes. The process continues to evolve with modern advancements in resin chemistry and automation, offering improved cycle times and consistent part quality.

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.

Only high-quality molds can produce high-quality products. Many times we will receive feedback from customers, “I don’t agree with the price of your injection mold, why is it so high?”. Such problems are mainly concentrated in non-professional mold technicians, who only calculate the average cost of the mold on the product, without real research and exploration, how important a high-quality mold is to the quality of the product and the progress of the overall project. We have many methods for low-cost molds, but we have lost 100% of the assurance of the quality of your products. The cost of the mold depends on the size, structure, material, product quantity and other special requirements of the part. For example: if you need 1,000 injection parts, then we will actively recommend that you choose a low-cost single-cavity mold, which can meet the quality and deliver the product on time. The most important thing is low-cost investment.
Blow molding is a process in which a hollow product formed by the expansion of a hot-melt plastic tube closed in a mold by means of gas pressure. The blow molding process was used to produce LDPE vials in World War II. In the 1950s, with the birth of HDPE materials and the development of blow molding machines, the blow molding process was widely used and the technology was upgraded. According to the different plastic blank tubes, it can be divided into extrusion blow molding, injection blow molding, stretch blow molding and multi-layer blow molding. Compression molding process A manufacturing process for molding polymers such as thermosetting plastics, thermoplastics, elastomers, rubber and plastic materials, and natural rubber. For example: children’s pacifiers, sealing rubber rings, power insulation parts, electrical enclosures, etc.
