Qimtek & Casting:

Casting Defined: Casting is a manufacturing process where a liquid material is poured into a mould, which contains a hollow cavity of the desired shape, and then allowed to solidify. At Qimtek, we connect industry buyers and design engineers seeking casting services with experienced UK-based suppliers. These suppliers use specialised techniques to mould materials like metal, plastic, and glass into precise shapes, guided by exacting standards. Qimtek acts as the intermediary, facilitating connections between those requiring casting services and those who provide them.

Process and Advantages: The casting process begins with melting the material, which is then poured into a molud. After cooling and solidifying, the material takes the shape of the mould. This method is advantageous for its ability to create complex shapes, high production volumes, and the versatility of working with a wide range of materials.

Industries and Applications: Casting is integral in numerous sectors, including automotive, aerospace, construction, and manufacturing of consumer products. These industries often require components with unique shapes and specific material properties.

Learn About: Casting 

This comprehensive guide delves into the intricacies of casting, a process integral to manufacturing and design. It explores different casting techniques, materials used, and their applications across various industries. The guide discusses the types of metals commonly used in casting, like aluminum, steel, and iron, along with non-metallic options. It also covers finishing processes, essential quality controls, and certifications typical for UK casting services. Additionally, the guide helps in identifying suitable casting service contracts and introduces renowned casting experts in the UK, offering insights into methods like sand casting, investment casting, die casting, and more.


Materials Suitable for Casting:

Casting accommodates various materials, each offering unique properties. Metals like aluminum, iron, and steel are widely used in automotive and construction industries. Non-metallic materials, including plastics and resins, cater to specific applications like prototypes and artistic creations. Here are 5 common materials used to cast bespoke components but you can discover more about the different options on our dedicated page.

  • Aluminum: Lightweight and highly versatile, aluminum is favored for its good strength-to-weight ratio and corrosion resistance. Common in automotive and aerospace parts.
  • Iron (Gray and Ductile): Gray iron is used for its excellent machinability and wear resistance, while ductile iron offers increased strength and toughness. Both are widely used in the automotive industry and for heavy machinery.
  • Steel: Known for its strength and durability, steel is used in various forms (like carbon steel and stainless steel) for applications requiring high resistance to wear and heat.
  • Bronze: An alloy of copper and tin, bronze is valued for its strength, wear resistance, and corrosion resistance. It's often used for bearings, bushings, and decorative items.
  • Zinc: Often used in die casting, zinc alloys are known for their high strength, ductility, and good impact resistance, making them suitable for small, intricate parts.

Casting Finishes:

Casted parts can receive numerous finishes to enhance their appearance and functionality. These include machining, painting, polishing, and plating, crucial for meeting specific project requirements. Our platform assists in connecting with suppliers specialising in casting your components and organising the finishing processes, ensuring parts meet precise specifications. 

  • Powder Coating: This finish involves electrostatically applying a dry powder, which is then cured under heat to create a tough, durable coating. Powder coating is popular for cast components due to its excellent corrosion resistance, wide range of colors and finishes, and ability to form a uniform layer over complex shapes.
  • Spray Painting: A traditional yet versatile finish, painting is commonly used on cast components to provide both protection and aesthetic enhancement. Spray painting offers a wide variety of colors and finishes, including high gloss, matte, and satin, and can be tailored for additional properties like UV resistance and improved durability.
  • Electroplating: This process involves coating the cast component with a thin layer of metal, such as chrome, nickel, or zinc, using an electrical current. Electroplating is chosen for its ability to enhance the appearance of the component, provide corrosion resistance, increase surface hardness, and in some cases, improve electrical conductivity.

Approvals for Casting Suppliers:

UK casting services often acquire various approvals and certifications to maintain quality and adhere to industry standards. Certifications like ISO 9001 for quality management and industry-specific certifications demonstrate a supplier's commitment to excellence. Using Qimtek to connect with certified casting manufacturers and foundries is straightforward, ensuring your projects meet the highest standards.For casting companies in the UK, the most relevant certifications typically focus on quality management, environmental standards, and industry-specific requirements. Here are the top three certifications a casting company might hold:

  • ISO 9001: Quality Management Systems: This certification is fundamental for casting companies. It assures that the company adheres to internationally recognized standards for quality management, ensuring consistent product quality and reliability. In the casting industry, where products often have critical applications in various sectors, maintaining high-quality standards is essential. ISO 9001 helps in streamlining processes, improving efficiency, and enhancing customer satisfaction.
  • ISO 14001: Environmental Management Systems: Given the significant environmental aspects of casting processes (such as energy use, waste management, and emissions), ISO 14001 certification is highly beneficial. It demonstrates the company's commitment to reducing its environmental impact and ensuring compliance with environmental regulations. This certification can also be advantageous in terms of operational efficiencies, cost savings, and corporate responsibility.
  • IATF 16949: Automotive Sector Quality Management System (replacing ISO/TS 16949): If the casting company supplies products to the automotive industry, IATF 16949 certification is crucial. This standard is specific to the automotive sector and is recognized globally. It includes requirements for a quality management system where an organization needs to demonstrate its ability to consistently provide products that meet customer and regulatory requirements. Given the critical nature of automotive components, adherence to these standards ensures reliability and quality in a highly competitive market.

Types of Casting Service Contracts:

Choosing the right casting service contract is crucial for aligning with your production needs. Options include On-Demand, Batch Production, Prototype Development, Custom Orders, Fixed-Price, and Time and Materials contracts. On-Demand offers flexibility, Batch Production optimises larger orders, Prototype Development is ideal for testing designs, Custom Orders cater to unique requirements, Fixed-Price ensures budget control, and Time and Materials offers adaptability. For casting companies, the top three service types that are especially beneficial to buyers of bespoke components are:

  • Custom Casting Projects: This service is ideal for producing custom-made, intricate designs that are not achievable through standard manufacturing processes. Custom casting allows for a high degree of complexity in shapes and is perfect for creating unique components with specific material properties. Buyers benefit from the ability to have parts tailor-made to their specifications, which is crucial in industries like automotive, aerospace, and artistic sculptures.
  • Small Batch Production: Small batch production is valuable for buyers who need a limited number of cast parts. This service is cost-effective for producing small quantities and is beneficial when the demand for parts is not high enough to justify mass production. It offers flexibility and a reduced upfront investment, making it ideal for custom projects, prototypes, or limited edition products.
  • Rapid Prototyping: Rapid prototyping in casting enables buyers to quickly get a physical model of their design. This is particularly useful for verifying the design and functionality of a part before moving to more expensive and time-consuming production stages. It's beneficial for industries where design accuracy and speed are critical, such as in product development, engineering, and design validation processes.
