Requirements and engineering come first
The project should define the grooming task, model, market, voltage, plug, blade, accessories, labeling and packaging. Engineering then checks whether the requested configuration and customization are feasible.
A controlled specification prevents product, artwork and compliance requirements from drifting apart.
Parts move into assembly
Housing components may be injection molded, while motors, batteries or power parts, blades, controls and fasteners are prepared for the selected model. Assembly stages should use the approved parts and work instructions.
PCS publicly describes injection molding, assembly, blade assembly, welding, heat-shrink sealing and packaging capabilities. The relevant route varies by product.
Functional checks connect production to evidence
Checks may occur during assembly and before packing. Buyers should ask which functions are checked, how results are recorded and how nonconforming units are handled.
A test performed on a sample or one model must not be generalized to every production unit or product family.
Packing closes the controlled order
Final packing should align the product, label, accessories, instructions and carton with the approved order. Shipment records help the buyer trace which configuration was supplied.
For an OEM or ODM project, the signed specification and transaction documents control over general website descriptions.
