Product Description

Overview of welding process for hardware parts

Our company has strong welding core competitiveness, and uses fully automatic equipment to flexibly accept parts welding processes from all walks of life. Various parts and components can be welded through copper loading, copper fetching, solder paste dripping, silver spot fetching, silver spot detection and positioning, silver spot welding, finished product fetching, and finished product fetching detection
 

Advantages and highlights of welding process equipment for hardware parts

1. The key process (mass production contact) adopts fully automatic production. Dynamic and static dual vision backup detection can effectively solve the problem of reverse spot and high penetration rate level in the industry by 90%.

2. Workshop welding equipment adopts medium frequency power supply, servo motor pressurization, automatic pressure detection display and automatic defect alarm, ensuring zero defect requirements for products

3. The welding process shall be standardized. Standardized electrode processing, standardized electrode use, standardized electrode maintenance and standardized data management completely solve the problem of unstable welding process

4. It has a number of key process technologies. Such as indirect heating resistance brazing process, induction brazing process and automatic welding after grinding (for welding problems of different materials).

5. The infrared temperature control technology is used to precisely control the welding parameters, which ensures the welding quality and greatly improves the service life of the product by 50%.

6. Side heating resistance welding process: the silver spot welding transfers heat from copper heating to silver spot welding. The silver spot has no electrical corrosion damage, which does not cause the silver spot surface to fade and become soft. It retains the original state of the silver spot. The contact has no damage, and the welding consistency is good, which increases the mechanical life and electrical life of the contact point by 15%.

7. In order to ensure the product quality, we check the leakage and make up for defects, and ensure the product quality, after the completion of welding, ultrasonic nondestructive testing, metallographic testing of welds, tensile testing, shear force testing and other means are used to comprehensively cover the elements of weld joint identification, and the quality risk of each period is strictly controlled through the first inspection, process inspection, completion inspection, factory inspection and other control means to ensure that the product leaves the factory with zero defects.

 

Welding process flow of hardware parts

Copper material-----punching and forming-----pickling-----surface treatment/electroplating of copper parts-----welding

 

 

Our after-sales rate of copper electroplating does not exceed 3 in 7 years.

1. After degreasing agent, pickling, cleaning, silver plating (the printing plate is converted into silver molecules by electrolysis, and then adsorbed on the copper by electrodes), cleaning, drying, drying at 100 ºC and other processes, the following parts are obtained.

2. Our copper electroplating silver content is up to 99.9999999%.

3. Through 7.5% potassium sulfide experiment, the time can be as long as 15 minutes, it solves the defects of unstable welding and discoloration of copper parts in the same welding process. The function is to ensure that the electroplated coating does not blacken and discolor within the specified time.

FAQ
1.Q: Are you trading company or manufacturer ?

3.Q: What is your terms of payment ?
   A: 30% T/T in advance ,and the balance before shipment.
 
4.Q : Can you make customized products or packing?
   A: Yes.We can offer customized products and packing ways can be made according to customer's requirement.

5.Q: Can you offer mould making services?
A: We have made many mould for different customers for years.Wecan offer DMC Thermosetting Compressionmoulding,Thermoplastic injection moulding,Metal stamping moulding.

6.Q: How about the guarantee period?
A: It varies according the different kinds of product. We can negotiate it before place an order.

7.Q: What is your production capacity?
   A: We can produce 3000  sets per month.

8.Q: How about the scale of your factory?
   A: Our total area is 7000 square meter. We have 300staffs, .40 engineers.
9.Q: What tests do you have to confirm the quality of the arc chamber?
   A: We have a incoming inspection for the raw material and process inspection for the rivet and stamping. There is also final statistical audit which consisting the measurement of sizes, tensile test and coat examine.

10.Q: What are the countries you have exported to?
A: We have not worked directly with foreign customers before, we provide ODM and OEM services for brands in China and then they take our products and sell them to foreign customers, basically to Europe and the Middle East.
11,Q: Your products are really good, but we have seen the same circuit breakers on the market nearby and their prices are much cheaper than yours.
A: First of all, I would like to emphasise that the price is definitely proportional to the quality. If you are a buyer, you must know that the materials and treatment processes used in our products are better than those of our peers, and the quality is recognised in the same industry. Our factory has a thermosetting workshop, thermoplastic workshop, welding workshop, hardware stamping workshop and assembly workshop, and the rate of self-made parts is as high as 80%. We have also built a new factory in Wuhu to guarantee the supply of parts for us, so that the parameters and various technical indicators such as mechanical life, Icu, Ics, etc. are very stable, and the match between parts is very high, and the service life of the finished product is also very long, which is They can be used in high-end industrial areas and hospitals, where the quality of the circuit breakers is very high. We also have our own technology patents and a very professional R&D team of 30-40 engineers to respond to the various needs of our customers, the development cycle of new products only takes 30-40 days, in the process, unconditionally provide you with technical expenses, we can greatly reduce the cost of communication and research and development costs. if particularly urgent, I can apply to my superiors to set up a customer line for you, specifically for you to assemble MCCB.
