The process of customizing CNC zinc alloy parts for the smart home industry usually includes the following key steps:
First, demand analysis and design
Demand analysis
Communicate with customers to clarify the use scenario, functional requirements, size specifications, material selection and quantity of parts.
Understand the customer’s specific requirements for the appearance, accuracy, performance, etc.
Design and modeling
According to customer requirements, use CAD software for 3D modeling of parts.
The simulation analysis of the model ensures that the structure of the parts is reasonable, the strength is enough, and the parts meet the requirements of use.
Determine the machining process route of the parts, including blank preparation, roughing, finishing, post-treatment and other steps.
Second, mold design and manufacturing
Mold design
According to the three-dimensional model of the parts, the corresponding mold structure is designed.
Considering the accuracy, life, ease of processing and cost of the mold and other factors, choose the appropriate mold material and manufacturing process.
Mold making
CNC machine tools, EDM and other high-precision equipment are used to manufacture molds according to design drawings.
Debug and inspect the mold to ensure that it meets the production requirements.
Third, blank preparation
Material selection
According to the requirements of the parts, choose the appropriate zinc alloy material.
Factors such as mechanical properties, casting properties, processability and cost of the material are considered.
Smelting and pouring
The zinc alloy material is heated to the melting state, the impurities are removed, and the composition is adjusted.
The molten zinc alloy is poured into the mold and cooled to produce blank parts.
Fourth, CNC machining
Rough finish
The blank parts are roughed using a CNC machine to remove most of the margin.
Determine the appropriate cutting parameters, such as cutting speed, feed rate, cutting depth, etc., to ensure processing efficiency and part quality.
semi-finishing
On the basis of rough machining, the parts are semi-finished to get closer to the final size and shape.
Prepare key parts before finishing, such as chamfering, deburring, etc.
finishing
Using high-precision CNC machine tools and tools, the parts are finished to achieve the dimensional accuracy and surface quality required by the design.
The key parts of the parts are finely polished and polished to improve the appearance quality and feel of the parts.
Fifth, post-processing and detection
Postprocessing
The finished parts are cleaned, deburring, rust prevention and other treatment.
According to customer requirements, surface treatment of parts, such as electroplating, spraying, painting, etc.
Quality inspection
The dimensional accuracy, shape accuracy and surface quality of the parts are tested comprehensively by using CMM, projector and other testing equipment.
Rework or scrap nonconforming products to ensure parts quality meet customer requirements.
Sixth, packaging and delivery
package
According to the shape, size and number of parts, choose the appropriate packaging materials and methods.
The parts are properly packed to prevent damage during transportation.
Deliver goods
Ship parts to the specified location at the time and place required by the customer.
Provide necessary shipping documents and after-sales service support.
Seventh, after-sales service
Parts instructions, installation guides and maintenance recommendations are provided.
Respond and deal with customer feedback in time to ensure customer satisfaction.
In the entire process of customized CNC zinc alloy parts, it is necessary to pay close attention to the needs and changes of customers, constantly optimize and improve the processing process and technical means, and improve the quality and performance of parts to meet the rapid development needs of the smart home industry.
