Assembly and packaging

Assembly Processes

Manual Assembly: Involves human intervention to assemble parts. This method is flexible but can be slow and prone to error.
Automated Assembly: Machines or robotic arms are used to assemble components. This method is more efficient and precise but requires high initial investment.
Semi-Automated Assembly: Combines both manual labour and machinery. This offers a balance between costs and productivity.

Types of Assembly Joints

Mechanical Joints: Components linked together using hardware like screws, nails or bolts. They are easily removable and adjustable.
Welded Joints: Parts fused together by applying high heat. They offer high strength but are permanent and may distort materials.
Adhesive Joints: Components joined using a bonding substance like glue or epoxy. They are cost-effective but can be affected by temperature and ageing.

Packaging

Primary Packaging: This is the first layer directly in contact with the product, like a soda can. It primarily focuses on product protection and convenience of use.
Secondary Packaging: The second layer that groups several primary packages together, such as a six-pack carton of soda cans. It aids in handling during distribution.
Tertiary Packaging: The external protection during shipping and warehousing. Typically composed of large boxes, pallets, or shrink-wrap.

Packaging Material Selection

Protection: The packaging material should be robust enough to protect against damage, contamination or tampering.
Regulation Compliance: Certain food, medicinal or hazardous materials need special packaging to meet laws and standards.
Economic: Packaging costs should be balanced against product value, distribution charges, and other economic concerns.
Usability: Ease of opening, convenience of use, and intuitiveness are all important factors for user satisfaction.
Environmental Factor: The ecological impact of packaging, including its recyclability and biodegradability, needs to be considered.

Quality Control in Assembly & Packaging

Inspection: Checking the assembly and packaging process at various stages for defects.
Sampling: Regularly taking a subset of output to check if it meets the quality standards.
Statistical Process Control: Using statistical methods to monitor and control the quality of processes.
Continuous Improvement: Involving the workforce in identifying and resolving issues that can affect the product quality.
