What are the advantages of good Dalian precision casting parts for improving motor performance?

2022-11-15

Tolerance is a very important part of any motor product. For the processing party with relatively weak production and processing capacity, the dimensional inaccuracy of its processing parts is relatively large, resulting in many nonconformities beyond the tolerance requirements, which naturally cannot guarantee the performance level of the whole product. What's more, because some parts are unqualified, it may be necessary to process one or more nonconformities that do not meet the drawing requirements because of this nonconformity, To complete the assembly of the motor, if this continues, the consistency of the motor parts will be very poor, which is extremely detrimental to the consistency of product performance, especially the guarantee of excellent performance.

How to effectively reduce the scrap rate of Dalian parts processing?

2022-11-18

In the process of processing, the current Dalian parts processing factory often pays more attention to some details and technological processes in the process, which is also what the manufacturer will pay more attention to, because it is related to whether the precision parts are finished products or waste products, which is an important guarantee of product quality.

What are the commonly used processing materials for Dalian machinery parts?

2022-11-18

The commonly used carbon structural steel is also called A3 steel. It has high plasticity, toughness, welding performance, cold stamping performance, certain strength and good cold bending performance. "Q" is the first letter of the pinyin of "Qu", representing the meaning of yield limit. "235" represents the yield value of the steel, about 235MPa. The following letter represents the quality grade. The quality grade is divided into four grades: A, B, C and D. The quality grade of Q235A steel is A.

Technological principle of vacuum precision casting in dalian

2022-11-18

The process principle of vacuum precision casting is to put the investment shell mold in the sealing chamber, the sealing chamber drops, the sprue is immersed in liquid metal, and then start the vacuum pump to vacuum the sealing chamber, and the liquid is cast at the same time.

What to pay attention to when cutting machining materials in Dalian

2022-11-15

When cutting Dalian machining materials, flame cutting is the basic cutting method. In order to achieve better cutting effect, there are many aspects that need attention in the setting of cutting process.

What materials are used to make molds for Dalian precision casting?

2022-11-15

Dalian precision casting uses fusible materials (such as wax or plastic) to make a fusible model (investment mold or model for short), which is coated with several layers of special refractory coatings. After drying and hardening to form a whole mold shell, the mold is melted off from the mold shell with steam or hot water, and then the mold shell is placed in a sand box, and the surrounding is filled with dry sand for molding, Finally, the mold is put into the baking furnace and baked at high temperature (for example, when using high-strength shell, the mold shell after demoulding can be directly baked without molding). After the mold or shell is baked, molten metal is poured into it to obtain the casting.
