Is the cost of powder metallurgy lower than ordinary cast parts?

The cost of powder metallurgy, can mass production reduce the cost? The cost of powder metallurgy includes many aspects, such as: raw material cost, labor cost, electricity cost, material waste cost, machine loss cost, time cost and other factors. Will the cost of mass production be lower than that of ordinary cast parts?

One: the cost of powder metallurgy

1: Material cost

The powder metallurgy process requires metal powder or some mixtures as raw materials, but the cost of raw materials in the entire powder metallurgy process only accounts for one-third, which is almost the same as the electricity cost during production.

2: Labor cost

Since powder metallurgy is a high-tech molding technology, every process such as mold design and production, mold assembly and adjustment, and sintering needs to be equipped with an engineer, and the cost of small batch production is relatively high.

3: Material waste cost

Powder metallurgy is a new type of near-net forming technology, which can reduce cutting or no cutting, and the utilization rate of materials can be as high as 95%. The cost of material waste is much more advantageous than traditional casting processes.

4: Time cost

It takes about 4 hours to process some complex precision parts by powder metallurgy process. With some subsequent post-processing and small details, the time cost is also a bit large. However, powder metallurgy can be mass-produced and the number of products is as high as several thousand. It reflects the time cost value of powder metallurgy, greatly shortening the time, and the accuracy is still high.

5: Machine loss cost

No matter it is any production and processing equipment, there will be the cost of this machine loss, which is inevitable.

Two: What are the advantages of powder metallurgy cost over ordinary casting parts cost?

Powder metallurgy can produce complex parts in large quantities (6000pcs), and can reduce machining or no cutting and up to 95% of the material utilization rate. It is easy to form and has high precision, which greatly reduces the waste of powder metallurgy materials, and also reduces The production cost, if it is a small batch of complex parts production, then the powder metallurgy component cost will be higher.

Three: How to reduce the processing cost of powder metallurgy?

It must be mass-produced, and the cost of powder metallurgy can be reduced by simplifying the structure of powder metallurgy parts as much as possible while satisfying the use of powder metallurgy parts.
