Best Group Design Engineer Interview Questions, Process, and Tips

Plastic wall thickness is decided based on factors like material properties, part geometry, and manufacturing process.

• Consider material properties such as strength, flexibility, and cost

• Evaluate part geometry to ensure structural integrity and proper function

• Take into account the manufacturing process to determine moldability and cost-effectiveness

Plastic tolerance chart standard provides guidelines for acceptable variations in dimensions for plastic parts.

• Plastic tolerance charts are based on the material type, manufacturing process, and part design

• They specify the acceptable range of dimensions for features like thickness, hole diameter, and length

• Tolerance values are typically expressed in +/- mm or percentage of the nominal dimension

• Common standards include ...read more

Plastic tolerance requirements vary depending on the specific part and its function.

• Plastic tolerance is typically specified in the design phase based on factors like material properties, part function, and assembly requirements.

• Tighter tolerances are often needed for parts that require precise fits or interfaces.

• Looser tolerances may be acceptable for parts that do not have critical dimensions or functional requiremen...read more

Plastic defects can be controlled through proper quality control measures and process optimization.

• Implement regular quality checks during production process

• Optimize processing parameters such as temperature, pressure, and cooling rate

• Train staff on proper handling and maintenance of equipment

• Utilize advanced technologies like sensors and automated inspection systems

• Collaborate with suppliers to ensure high-quality raw
