Assembly Department (English Version)

🔩 I. Core Positioning of the Process

The Assembly Department is the final forming link of hardware accessories from "parts" to "finished products", undertaking polished/plated parts upstream and connecting to the quality inspection and packaging workshop downstream.

Core Objectives:

Assemble individual parts (buckle bodies, rivets, springs, snap fasteners, etc.) into complete, functionally qualified finished accessories (such as D-rings, locks, side-release buckles).
Complete initial functional inspection simultaneously to prevent defective products from flowing downstream.

🔧 II. Equipment & Process Analysis

Core Equipment: Foot-operated Small Punch Press / Pneumatic Riveting Machine

Function: Complete riveting, pressing, punching, bending and other actions through set pressure, serving as the main equipment for assembly.

Advantages: Stable pressure, simple operation, suitable for assembling small parts of luggage hardware, high efficiency and ideal for mass production.

Key Control: Adjust pressure and stroke according to part material and thickness to avoid loose riveting or part damage.

Assembly Process Flow

Part Preparation: Collect polished/plated parts according to order batches, check models and quantities to avoid mixing materials.
Trial Assembly & Debugging: First trial-assemble a small number of products to confirm part matching and whether the punch press pressure is appropriate.
Mass Assembly: Workers operate in accordance with SOP, put parts into molds, and step on the pedal to start the punch press for riveting/pressing.
Initial Functional Inspection: After assembly, test whether opening/closing, pressing and rebound are smooth, and whether the structure is firm.
Classification & Transfer: Qualified products are placed in pallets and sent to the quality inspection and packaging workshop; defective products are marked separately for rework or scrapping.

⚠️ III. Key Management & Safety Points

Quality Control

Riveted parts must undergo random tensile testing to ensure riveting strength meets standards and no detachment occurs.
Parts matching must be consistent to avoid the problem of "inconsistent opening/closing feel of products in the same batch".
100% initial functional testing is required; defective products are strictly prohibited from entering the next process.

Safety Specifications

Protective gloves must be worn when operating the punch press; hands are strictly prohibited from entering the mold area.
Equipment must be equipped with safety shields, and foot switches must be sensitive and reliable to avoid misoperation.
Equipment must be regularly maintained, and molds and pressure systems must be inspected to prevent accidents or product damage caused by malfunctions.

Efficiency & On-site Management

Part and finished product pallets beside workstations must be placed in separate areas and marked by batch to avoid batch mixing.
Adopt assembly line layout to reduce material handling distance and improve transfer efficiency.
Defective products must be stored and marked separately; rework rate is counted regularly to trace the source of problems.
