Injection Moulding
This is the most common method. Molten plastic is injected into a mould, which is then cooled and opened to release the finished product. It's used for mass production of parts with complex shapes.
-
Blow Moulding
Used primarily for making hollow objects like bottles. In this process, air is used to inflate soft plastic into a mold cavity.
-
Rotational Moulding
This method is used for creating large, hollow parts. Plastic powder is placed inside a mold which is then heated and rotated, causing the plastic to melt and stick to the walls of the mold.
-
Compression Moulding
Great for large, fairly simple parts. Here, plastic is placed into a heated mold cavity and then the mold is closed with a top plug, applying pressure to shape the material.
-
Thermoforming
Sheets of plastic are heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product, such as packaging materials.
-
Vacuum Forming
A simplified version of thermoforming where a sheet of plastic is heated, stretched onto a single-surface mold, and forced against the mold by a vacuum.
-
3D Printing
Creating three-dimensional objects layer by layer from digital designs, widely used for rapid prototyping and complex part production.
-
Plastic Machining
Plastic machining shapes solid plastic through precision cutting. Using tools like CNC machines, it carves detailed, accurate parts from plastic blocks or sheets.

Learn About: Plastic Moulding
This guide delves into the diverse techniques and specifics of plastic moulding, outlining the processes, their benefits, and their application across various industries. It emphasises the suitable materials for plastic moulding, finishing methods, and the certifications commonly held by UK plastic moulding companies. The page also explores different types of service contracts for plastic moulding projects and guides on selecting the most fitting one for particular needs. It concludes with insights into various plastic moulding techniques including including injection moulding, vacuum forming and 3D printing, amongst others and their distinct features and applications.
What plastics can you use to manufacture?
Common materials in plastic moulding include polyethylene, polystyrene, and ABS, each chosen for their unique properties like durability, flexibility, and impact resistance. Qimtek connects you with experienced plastic manufacturing companies skilled in working with these materials, ensuring your project's specific requirements are met. Three plastics commonly used in plastic molding are:
- Polypropylene (PP): Known for its flexibility, chemical resistance, and toughness, polypropylene is widely used in packaging, automotive parts, and consumer goods.
- Polyethylene (PE): Including variants like High-Density Polyethylene (HDPE) and Low-Density Polyethylene (LDPE), it's renowned for its durability, impact resistance, and versatility. Commonly used in containers, pipes, and household items.
- ABS (Acrylonitrile Butadiene Styrene): A strong, durable thermoplastic, ABS combines the strength of styrene polymers with the toughness of polybutadiene rubber. It's commonly used in automotive parts, electronic housings, and toys.
What finishes can you apply to plastics?
For plastic moulded products, which can be made from various types of plastics and often require finishes to enhance appearance, durability, or functionality, the three most common finishes applied are:
- Painting: This is a widely used finishing technique for plastic moulded products to enhance their aesthetic appeal. It allows for a broad range of colours and finishes, including matte, glossy, and textured surfaces. Specialised paints can also provide additional properties like UV resistance and increased durability.
- Plating (Electroplating or Chrome Plating): Although more complex, plating can be applied to certain types of plastics, often through a process known as electroless plating. This finish is used to give plastic parts a metallic look and can also add qualities like improved wear resistance and electrical conductivity.
- Texturing: During the moulding process, textures can be applied directly to the mould surface, imparting various patterns and finishes to the plastic product. This not only enhances the tactile and visual appeal but can also hide imperfections and improve grip. Post-moulding, techniques like sandblasting or laser etching can also be used to create or refine textures on plastic surfaces.
Approvals held by plastic manufacturers.
For plastic molding companies in the UK, certifications and standards are crucial to ensuring the quality of their products and processes. Here are the top three certifications and standards that plastic molding companies should consider:
- ISO 9001: Quality Management Systems: ISO 9001 certification is essential for plastic molding companies. It demonstrates that the company has established and maintains a robust quality management system. In the plastic molding industry, precision, consistency, and product quality are critical. ISO 9001 helps ensure that processes are controlled, and products meet specific quality criteria, enhancing customer satisfaction and continuous improvement.
- ISO 14001: Environmental Management Systems: Given the environmental aspects of plastic molding processes, ISO 14001 certification is highly beneficial. It showcases the company's commitment to environmental responsibility and compliance with environmental regulations. Plastic molding companies can benefit from operational efficiencies, cost savings, and a positive environmental reputation.
- ISO 13485: Medical Devices - Quality Management Systems: If the plastic molding company manufactures components for the medical device industry, ISO 13485 certification is essential. It sets specific quality management standards for the design and manufacturing of medical devices. Compliance with ISO 13485 demonstrates a commitment to product safety and quality in a highly regulated industry.
Contracts plastic manufacturers offer
Selecting the appropriate plastic moulding service contract is essential for fulfilling your production needs. For plastic molding companies, three common service types that are especially beneficial to buyers of bespoke components are:
- Full-Scale Production: Full-scale production services provide buyers with the capability to manufacture plastic components in large quantities. This service is ideal for projects that require a high volume of consistent parts. Buyers benefit from cost-effective production processes that optimise efficiency and minimise per-unit costs.
- Prototype Development: Prototype development in plastic molding enables buyers to quickly create physical models of their designs for testing and validation. It's particularly useful for product development and design refinement, reducing the risk of errors in the final product. Buyers can iterate and make adjustments before moving to full-scale production.
- Low-Volume Production: Plastic molding companies can efficiently handle low-volume production runs. This service is cost-effective for buyers who need a limited quantity of plastic components without the need for expensive moulds or tooling. It's advantageous for custom or specialised products where production volumes are not high enough to justify mass production.
