The reducer is a relatively precise machine. The casing is the casing of the reducer. The arrangement of its heat treatment process in the process line mainly depends on the purpose of heat treatment. Arrangement information of heat treatment process of reducer housing:
1. The heat treatment annealing and normalizing of the reducer housing are usually arranged before rough machining. Their main purpose is to improve the cutting performance of materials and eliminate internal stress.
2. Quenching. It is divided into overall quenching, surface quenching and carburizing quenching. It is generally arranged between finishing and semi finishing. Quenching, tempering and normalizing treatment are often carried out before surface quenching. The purpose of quenching is to make the parts obtain high hardness and wear resistance.
3. Aging treatment. General castings are usually arranged after rough machining. High precision complex castings shall be arranged once before and after semi finishing. Precision parts with poor rigidity shall be subject to aging treatment for several times during rough machining, semi finishing and finishing. The purpose of aging treatment is to eliminate the internal stress generated in blank manufacturing and machining, and stabilize the accuracy of parts.
4. Fade. Arranged before fine grinding. Quenching and tempering treatment shall be arranged before desalination to improve the hardness, wear resistance, fatigue strength and corrosion resistance of parts.
5. Quenching and tempering are generally arranged after rough machining and before semi finishing. The better comprehensive mechanical properties of the parts obtained by quenching and tempering can also refine and compact the metal structure, making preparation for reducing deformation by quenching and nitriding in the future
Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
How to provide goods?
Usually we will ship the goods to the sea. The factory is only 460 kilometers away from the port. It is very convenient and convenient to transport the goods to any other country. Of course, if your cargo is very urgent, Ningbo Airport and Shanghai Airport are also nearby.
What is the payment term?
When we provide you with a quotation, we will negotiate with you: EXW, FCA, FOB, CIF, CRF, DAP Etc. For mass production, you need to pay 30% of the deposit before production and 70% of the balance before shipment. Our most common way is T/T.
How to ensure the quality of your products?
First, we will check after each process. For finished products, according to customer requirements and international standards.
How many employees does your company have? What is the relationship between technicians?
We now have more than 180 employees, including 36 engineers and 28 QCs.
What is the ability of your company?
We have a number of production lines with a monthly production capacity of 1,600 units and an annual production capacity of 20,000 units.
