Common Problems and Solutions for Custom Components

Custom Components: Problems and Solutions at the Design Stage

Excessive Size Deviation

• Problem Cause: Lack of detailed labeling in design drawings, or failure to consider machining tolerances and assembly requirements.
• Solution: Strictly label key dimensions and tolerance requirements at the design stage, and use CAD software for simulation and calibration.

Unreasonable Structural Design

• Problem Cause: Designers do not have a sufficient understanding of the usage scenario or load requirements of the parts, resulting in insufficient strength or function.
• Solution: Communicate fully with the customer about the usage requirements, and conduct FEA to evaluate the reasonableness of the structural design.

Ignoring Manufacturing Process Constraints

• Problem Cause: The design solution does not take into account the feasibility of the manufacturing process, e.g. complex geometries that are difficult to machine.
• Solution: Work closely with the production team during the design process to optimize the design using DFM principles.

Custom Components: Material Selection Problems and Solutions

The material does not Match the Application Requirements

• Problem Cause: Insufficient consideration of the mechanical properties, corrosion resistance, or temperature adaptability of the material.
• Solution: Analyze the material properties according to the application environment and select the appropriate metal, plastic or composite material.

Excessive Material Costs

• Problem: High-performance materials are selected but not fully utilized, resulting in wasted costs.
• Solution: Balance performance and cost and choose more cost-effective materials, such as heat treatment or surface coating to enhance the performance of common materials.

Custom Components: Problems and Solutions at the Production Stage

Insufficient Machining Accuracy

• Problem Cause: Equipment accuracy or operation process does not meet the requirements, resulting in parts with excessive errors.
• Solution: Regular calibration of processing equipment and strict quality control process.

Low Production Efficiency

• Problem Cause: Process flow design is unreasonable, or the degree of automation of equipment is low.
• Solution: Optimize the process flow, and adopt automated equipment or robots to assist production.

Surface Quality Defects

• Problem Cause: Improper cutting parameters during machining, or insufficient surface treatment technology.
• Solution: Adjust the cutting parameters and select suitable surface treatment technology (e.g. sandblasting, electroplating or anodizing).

Custom Components: Problems and Solutions in the Assembly and Use Stages

Poor Assembly

• Problem Cause: Poor tolerance matching of parts or insufficient consideration of the assembly process.
• Solution: Carry out assembly simulation before production to ensure the size matching of parts and the feasibility of the assembly process.

Short Service Life

• Problem Cause: Material or structure does not meet the demands of long-term use.
• Solution: Optimize the design for the operating environment, e.g. by adding protective coatings or improving load distribution.

Custom Components: Quality Control Problems and Solutions

Poor Batch Product Consistency

• Problem Cause: High fluctuation of process parameters during production, or lack of standardized processes.
• Solution: Implement Statistical Process Control (SPC) and automated monitoring at key process points.

Delivery Delays

• Cause: Improper supply chain management or unreasonable production plan.
• Solution: Establish a good communication mechanism with suppliers, optimize production scheduling, and reserve safety stock.
