Fabrication & Assembly at Protec Group: Precision, Versatility, and Expertise in Metalworking

At Protec Group, we specialise in high-precision metal fabrication and assembly, delivering custom-engineered solutions for industries including automotive, defence, and aerospace. Our advanced techniques ensure top-quality components, from prototyping to full-scale production, with a focus on efficiency, durability, and cost-effectiveness. We leverage a wide range of fabrication methods — including welding, CNC bending, and advanced cutting techniques — to meet the specific needs of our clients.

Laser Cutting for Precision Profiles

Laser cutting is an efficient and accurate technique for profiling sheet metals. Our state-of-the-art laser systems use focused beams to achieve clean, precise cuts with minimal waste. This technology is ideal for creating intricate designs with tight tolerances and smooth edges, making it perfect for low to medium-volume production in materials like mild steel, stainless steel, and aluminium.

Waterjet Cutting for Complex Materials

Waterjet cutting is a cold-cutting process that uses a high-pressure jet of water mixed with abrasive particles. This method allows us to cut heat-sensitive materials without distortion, ensuring that the material’s structural integrity is maintained. Waterjet cutting is versatile and can be used to process a wide range of materials, from metals to composites, with exceptional accuracy and clean finishes.

CNC Bending for Custom Forming

CNC bending and folding are essential for shaping metal into complex parts, such as brackets or enclosures. Using advanced CNC press brakes, we can create precise bends and folds in various materials and thicknesses. This process guarantees consistency and repeatability across production runs while offering the flexibility to create custom geometries for highly specialised applications.

Hammer Forming for Custom Prototypes

Hammer forming is a traditional yet highly effective technique used for creating complex shapes in low-volume production. By carefully shaping metal over a die using manual hammers or mallets, this method offers flexibility and allows for fine adjustments. It’s an ideal solution for prototyping or producing one-off components that require a high level of craftsmanship.

Welding for Structural Integrity

Welding plays a crucial role in ensuring the structural strength and longevity of fabricated components. At Protec Group, we use various welding methods, including MIG, TIG, and spot welding, tailored to the material type and project requirements. Whether it’s joining thin sheet metal or assembling heavy-duty structures, we provide clean, strong, and durable welds for a wide range of industrial applications.

Fixing and Fastening for Reliable Assemblies

Mechanical fixing methods are key to creating secure, robust assemblies. We offer a full range of fastening options, including threaded inserts, rivets, clinch nuts, and PEM® fasteners. These components are applied using specialist press systems, ensuring that they meet the required load-bearing capacity and provide reliable, long-lasting connections.

Case Study: Automotive Bracket Fabrication

A leading automotive manufacturer requires a custom bracket for a centre console. The process begins with laser cutting, where the bracket’s shape and features are precisely cut from sheet metal. It then undergoes CNC bending to achieve the correct form. Once shaped, the bracket is e-coated for corrosion resistance. Press-fit inserts are added for easy assembly, and the part is incorporated into the full assembly of the centre console. This streamlined process guarantees high-quality results, reduced production time, and seamless integration into the customer’s production line.
