Injection Molding Process\nInjection molding is the most widely used plastic forming method. Injection molding machines use molds to shape thermoplastic or thermosetting plastics into various plastic products.  \n\nIt’s similar to playing with clay as a child: put a lump of clay (plastic melt) into a shaped box (mold), press it down (clamping and injection), then open the lid (mold opening) to get the desired product.  \n\n![Injection Molding Process Diagram showing the steps of melting, injecting, clamping, cooling, and demolding thermoplastic material](https:\u002F\u002Fassets.chinareleaseagent.com\u002Fuploads\u002F_2fe9e85804.jpg)\n\n---\n\n## 2. Extrusion Molding Process\nExtrusion molding pushes the material through the barrel and screw of an extruder. The material is heated and plasticized while being pushed forward, then continuously shaped through the die to produce semi-finished products, commonly used for pipes and sheets.  \n\nThink of squeezing toothpaste: when you push the tube (screw feeding), the toothpaste (polymer melt) comes out in a cylindrical or other shapes.  \n\n![Extrusion molding process diagram showing plastic material being heated, plasticized, and pushed through a screw and die to form continuous shapes like sheets or pipes](https:\u002F\u002Fassets.chinareleaseagent.com\u002Fuploads\u002F_254799204d.jpg)\n\n---\n\n## 3. Blow Molding Process\nAlso known as hollow blow molding, this rapidly developing method uses a tubular plastic preform made by extrusion or injection. After heating to soften, it is placed in a mold, then compressed air is injected to expand the plastic against the mold walls. After cooling and demolding, various hollow products such as bottles are obtained.  \n\nThis process is like making square watermelons: an oval-shaped preform (plastic tube) is placed in a square mold, then expanded (blown) into the mold shape, resulting in a square-shaped watermelon (bottle).  \n\n![Blow molding process diagram showing a heated plastic preform expanded inside a mold using compressed air to form hollow products like bottles](https:\u002F\u002Fassets.chinareleaseagent.com\u002Fuploads\u002F_ba63b2ed4a.jpg)\n\n---\n\n## 4. Vacuum Forming (Thermoforming) Process\nThis technique heats a flat plastic sheet until soft, then uses vacuum suction to pull it onto a mold surface. After cooling, it retains the mold shape. This process is widely used in various industries.  \n\nIt’s like making a fried egg: the liquid egg (softened plastic sheet) is poured into shaped cookware (mold), heated (softened by vacuum), and cooled to form the desired shape.  \n\n![Vacuum forming process diagram showing a heated plastic sheet being softened and pulled onto a mold surface using vacuum to create shaped plastic parts](https:\u002F\u002Fassets.chinareleaseagent.com\u002Fuploads\u002F_ce3f58b830.jpg)\n\n---\n\n## 5. Compression Molding Process\nAlso called press molding, this method places powdered, granular, or fibrous plastic into a heated mold cavity. The mold is closed, and pressure is applied to form and cure the product. Suitable for thermosets, thermoplastics, and rubber materials.  \n\nSimilar to injection molding but primarily for thermosetting resins: place the material in a shaped mold, apply heat and pressure, then cool to get the finished product.  \n\n![Compression molding process diagram showing powdered or granular plastic placed into a heated mold cavity, pressed, and cured to form a finished plastic part](https:\u002F\u002Fassets.chinareleaseagent.com\u002Fuploads\u002F_eb935eb992.jpg)\n\n---\n\n## 6. Calendering Process\nCalendering passes heated thermoplastic material between two or more counter-rotating rollers, stretching and compressing it into sheets of required dimensions and quality, then allowing it to cool naturally. Often used for plastic films or PVC sheets.  \n\nCompared to extrusion, calendering uses rollers to thin and shape the extruded material.  \n\n![Calendering process diagram showing heated plastic material passing through counter-rotating rollers to form thin sheets or films](https:\u002F\u002Fassets.chinareleaseagent.com\u002Fuploads\u002F_83f6fdde78.jpg)\n\n---\n\n## 7. Foam Molding Process\nFoam molding introduces a blowing agent into materials such as PVC, PE, or PS to create a microcellular structure. Almost all thermosetting and thermoplastic plastics can be foamed, making this an important plastic processing field.  \n\nSimilar to making steamed buns: adding baking powder (blowing agent) causes the dough (material) to expand with gas bubbles during heating. In plastics, gas injection can also replace chemical foaming.  \n\n![Foam molding process diagram showing plastic material with blowing agent forming microcellular foam structures during heating and expansion](https:\u002F\u002Fassets.chinareleaseagent.com\u002Fuploads\u002Fblog_0130_6_50a1b14340.webp)\n\n---\n\n## 8. Filament Winding Process\nThis technique wraps continuous fibers (or prepregs, tapes) impregnated with resin around a mandrel according to a specific pattern. After curing and demolding, the final product is obtained.  \n\n![Filament winding process diagram showing continuous fibers or prepregs soaked in resin being wound around a mandrel to form composite products](https:\u002F\u002Fassets.chinareleaseagent.com\u002Fuploads\u002Fblog_0130_1_991e4b7398.webp)","2026-01-30T06:04:58.082Z","2026-09-12T02:11:00.638Z","2026-01-30T06:55:26.667Z","16-types-of-plastic-processing-techniques-part-1","16 Types of Plastic Processing Techniques (Part 1)","Plastic molding starts with the right process selection and succeeds with smooth demolding.
