Assembly and finishing techniques
- Fastening is the act of joining parts together by means such as nails, screws, or glue. It also includes using clips or staples, mainly used in furniture and construction.
- Mechanical fasteners are used to temporarily join or detach components, such as nuts, screws, and bolts.
- Pinning involves inserting a pin into two or more pieces to bind them securely. This can help create permanent or semi-permanent bonds.
- Riveting involves driving a metal pin or bolt through items to join them.
- This process provides a strong joint that is resistant to loosening and can bear a significant amount of load.
- Adhesives can bond materials, such as paper, plastic, wood, metal, and glass.
- Adhesives can be applied in various ways, including coating, spraying, or brushing onto the surface.
- Soldering is a method of joining metal pieces by melting a filler metal into the joint.
- Brazing is similar to soldering but at higher temperatures, creating strong joints in metal parts.
- Grinding smooths the edges of a product and removes any small pieces of material remaining after assembly.
- Painting protects the surface, adds colour or design, and impacts the product’s overall aesthetics.
- Different techniques can be used, including spray painting, powder coating, and electrocoat or e-coat.
- Polishing involves refining a surface to a smooth or mirror-like condition.
- This could be done using a range of abrasives, chemical polishes, or buffing wheels.
- In plating, a thin layer of metal is deposited onto the surface of an object. This improves appearance, corrosion resistance, and wear resistance.
- Types of Plating include electroplating, electroless plating and immersion plating.
- Lacquering forms a protective coating on the product that is often glossy and prevents oxidation, wear, and adds aesthetics.
- Sandblasting is a method of cleaning or roughening a surface by blasting it with sand.
- This method can also be used to impart a texture or design onto the surface of a product.
Inspection and Testing
- Inspection involves examining the finished product to ensure it meets the desired specifications and quality standards.
- Testing could be mechanical, electrical, or environmental, to ensure the product can withstand conditions it might be exposed to in its functional life.
- Good record keeping is crucial for tracing issues, demonstrating responsibility, and improving future processes.
- This includes information about each step in the assembly and finishing process, the materials used, test results, and any issues or adjustments made.
Feedback and Improvement
- In a well-functioning operation, there should be a continuous loop for feedback and improvement.
- This includes seeking feedback from various sources, analysing problem areas to root causes, then implementing this feedback to improve the processes.
