Manufacturing Engineering

Stamping and stretching workshop

1. Sheet metal cutting and preparation

According to product requirements, the stainless steel sheet is cut into a suitable size and the surface is cleaned to ensure smooth subsequent processing.

2. Stamping (preliminary forming)

puts the metal plate into the mold and initially stretches it through the punch to form the basic shape. Depending on the complexity of the product, multiple presses may be required.

3. Stretch Forming

use deep-drawing equipment to stretch the metal sheet to the target shape to ensure uniform thickness and meet design requirements.

4. Edge Trimming

Use cutting or trimming equipment to trim the edges of the formed workpiece to remove excess material and improve accuracy.

5. Welding and Assembly

According to the design requirements, argon arc welding or laser welding technology is used to weld different parts together to ensure a stable structure.

6. Hand polishing and mechanical grinding

Skilled technicians combined with automatic polishing equipment to carefully polish the surface of the workpiece to make it smooth and flawless, showing a high quality metallic luster.

wax casting workshop

1. Mold development

According to the design drawings, the production of high-precision mold, to ensure that the shape and size of the subsequent wax mold meet the product requirements.

2. Wax model making

injected into the mold, and the mold is released after cooling to form a wax mold consistent with the product.

3. Wax mold assembly

connecting multiple wax molds into a tree-shaped pouring system, it ensures smooth flow of metal during pouring and improves production efficiency.

4. Fabrication of pottery shell

repeatedly dipping wax patterns into refractory slurry and sprinkling refractory sand, a strong ceramic shell is formed for the casting process of withstanding high temperature metals.

5. Dewaxing

melted and removed by high temperature steam or hot water treatment, leaving a cavity for pouring metal.

6. Metal pouring

injecting molten stainless steel or other metal into the preheated ceramic shell mold cavity.

7. Removal of ceramic shell

After cooling, the ceramic shell is removed using vibration or high-pressure water flow to expose the prototype of the metal casting.

8. Hand Trimming and Polishing

finish and grind castings to ensure a clean finish and accurate detail.

9. Quality inspection

In the process of precision wax casting, in order to ensure the quality of incoming materials and the performance of finished products, it is necessary to use a variety of testing instruments to carry out strict testing.

The following is a list of commonly used incoming inspection and finished product inspection instruments:

Incoming material testing instrument

Spectrum Analyzer (Spectrometer)

Purpose: Detect the chemical composition of metal materials to ensure that the alloy composition meets the design requirements.

Application: Mainly used for composition analysis of stainless steel, titanium alloy and other materials.

Hardness Tester (Hardness Tester)

Purpose: Test the hardness of metal raw materials to ensure that the processing performance requirements are met.

Common types: Rockwell hardness tester, Vickers hardness tester, Brinell hardness tester.

ultrasonic flaw detector (Ultrasonic Flaw Detector)

purpose: to detect whether there are defects such as cracks or pores in the raw materials.

application: suitable for large size metal block or plate.

metallographic microscope (Metallographic Microscope)

Purpose: Observe the internal structure of the material to verify whether the material meets the requirements.

applications: for analyzing grain size and distribution.

Thickness Gauge (Thickness Gauge)

purpose: to measure the thickness of the metal sheet is uniform, to ensure the accuracy of processing.

common types: ultrasonic thickness gauge, mechanical thickness gauge.

Surface Roughness Tester (Surface Roughness Tester)

Purpose: To detect the flatness and roughness of the surface of the raw material to ensure the smoothness of the subsequent processing.

electronic balance (Electronic Balance)

use: used to accurately measure the weight of wax and metal blocks to ensure accurate matching.

Finished product testing instrument

coordinate measuring instrument (CMM-Coordinate Measuring Machine)

Purpose: High-precision measurement of size, shape and position tolerances of castings.

Application: Ensure that castings meet the dimensional requirements of design drawings.

X-ray flaw detector (X-Ray Detector)

purpose: to detect whether there are pores, cracks and other defects inside the casting. Application: Suitable for metal castings with high precision and high requirements.

NDT equipment (NDT-Non-Destructive Testing)

include:

magnetic particle flaw detector (Magnetic Particle Inspection)

: Detect surface and near surface defects.

penetration detector (Dye Penetrant Testing)

: Detect surface cracks and holes.

purpose: to detect surface and near surface defects.

Hardness Tester (Hardness Tester)

Purpose: Test the hardness of castings to ensure that the material properties meet the requirements.

tensile testing machine (Tensile Testing Machine)
