Lamination Process\nLamination combines multiple layers of the same or different materials under heat and pressure into a single product. It is commonly used for plastics and rubber.  \n\nThis process is similar to compression molding but allows for multi-layer structures, whereas compression molding typically works with single-material, single-structure products.  \n\n![Lamination process diagram showing multiple layers of plastic or other materials being combined under heat and pressure to form a single product](https://assets.chinareleaseagent.com/uploads/blog_0130_2_97c0137abc.webp)\n\n---\n\n## 10. Coating / Surface Coating Process\nThe coating process applies plastic or organic solutions onto substrates such as fabric or paper to produce synthetic leather, coated fabrics, or plastic wallpapers. Powder coating on metal surfaces is also part of this process.  \n\nFor example, melted resin is applied to a substrate surface, then cooled and solidified to form the desired product. This process is mainly used for large, flat plastic items.  \n\n![Coating process diagram showing plastic or resin applied onto substrates like fabric, paper, or metal to create synthetic leather, coated fabrics, or decorative surfaces](https://assets.chinareleaseagent.com/uploads/blog_0130_3_cd80f06010.webp)\n\n---\n\n## 11. Casting Process\nCasting involves pouring liquid raw materials into a mold at atmospheric pressure. The material undergoes polymerization or curing to form a product that matches the mold cavity shape. Modern casting processes can also use PVC pastes or polymer melts.  \n\nOriginally developed for thermosetting plastics, casting later expanded to thermoplastics. Uncured material is placed into a mold and stimulated to react and harden, similar to the square watermelon analogy used in blow molding.  \n\n![Casting process diagram showing liquid plastic material poured into a mold cavity and solidified to form a shaped plastic part](https://assets.chinareleaseagent.com/uploads/_45348272d4.jpg)\n\n---\n\n## 12. Drip Molding Process\nThis method utilizes the property of thermoplastic materials that allows them to flow when heated and solidify at room temperature. Melted material is dripped using specific tools to create shapes, then cooled to solidify.  \n\nFor thermoplastic resins, this process is similar to melting wax and dripping it into molds, where it forms shapes after cooling.  \n\n![Drip molding process diagram showing thermoplastic material in a fluid state being dripped onto a mold and solidified to form shaped parts](https://assets.chinareleaseagent.com/uploads/blog_0130_4_af2e9763bd.webp)\n\n---\n\n## 13. Compression Thermoset Molding Process\nThis process is mainly used for thermosetting plastics. The material is heated until it melts, pressed inside a mold, cross-linked under heat, and then demolded to obtain the finished part.  \n\n![Compression thermoset molding process diagram showing heated thermoset plastic being pressed in a mold, cured, and demolded to form a finished part](https://assets.chinareleaseagent.com/uploads/_e70e0569b5.jpg)\n\n---\n\n## 14. Extrusion Press Molding Process\nExtrusion press molding is a pressure-forming method in which a punch or die compresses material inside a mold, causing plastic flow to conform to the mold cavity shape.  \n\nEven materials with low plasticity can be formed using this method. Unlike blow molding, shaping relies on mold pressure rather than compressed air.  \n\n![Extrusion press molding process diagram showing plastic material being pressed in a mold using a punch or die to flow into the desired shape](https://assets.chinareleaseagent.com/uploads/_7b5568e4a3.jpg)\n\n---\n\n## 15. Thermoforming Process\nThermoforming shapes heated thermoplastic sheets into products by softening the sheets and pressing them into molds. After cooling, trimming produces the final parts.  \n\nThis process is similar to blow molding but starts with flat sheets instead of tubular preforms.  \n\n\n![Thermoforming process diagram showing heated plastic sheets being shaped over a mold under external force and cooled to form final plastic parts](https://assets.chinareleaseagent.com/uploads/_676bae0958.jpg)\n\n---\n\n\n## 16. Hand Lay-Up Molding Process\nAlso known as manual lay-up or contact molding, this process involves placing reinforcement materials into a mold coated with release agent. Resin is then applied by hand until the required thickness is achieved.  \n\nAfter curing and demolding, the finished composite part is obtained.  \n\n![Hand lay-up molding process diagram showing resin being applied by hand onto reinforcement material in a mold and cured to form composite parts](https://assets.chinareleaseagent.com/uploads/blog_0130_5_71cd7a3909.webp)\n\n---\n\n## Conclusion\nUnderstanding processing methods creates value, while smooth production converts that value into output. Whether using injection molding, extrusion, or hand lay-up molding, mold sticking remains one of the largest hidden losses in production.  \n\nWe understand this challenge and focus on developing efficient, environmentally friendly release agent solutions. Perfecting the process is your expertise—ensuring every mold opens smoothly is ours.\n","2026-01-30T07:28:01.948Z","2026-03-04T13:48:39.061Z","2026-02-06T15:38:52.179Z","16-types-of-plastic-processing-techniques-part-2","16 Types of Plastic Processing Techniques (Part 2)","In last week’s blog post, we introduced eight plastic processing techniques.
