  tungsten carbide cold heading dies

1. About raw materials and powder:

Soon after the order is confirmed, our production will start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine.

 

 

 

2. About pressing:

1).How do Mingri start a production? How do we check?

Before mass production, we need to do a trial pressing and sintering using every mould, and we check the appearances and the sizes of the samples with micrometer, projectors etc. to ensure that the requirements of the drawings can be met before batch production;

 

 

3. About Furnace:

1).How many furnaces?

10 sets of vacuum sintering furnace and 1set of HIP

10 sets of sintering furnace and one set of HIP in the factory ensure the best quality and production capacity.

 

4. About cleaning/tumbling :

1). cleaning/tumbling is to make the products look more beautiful.

2).The goods can be ground according to customers’ order to a tolerance of +/-0.05

 

5 About laboratory:

1.How do you produce samples for control?

We sample each batch RTP into pressing and sintering, only when certificated by the laboratory, the RTP can be put into mass production.

 

 

6. About Packing :

The cargo can be packed with internal paper boxes and then external cartons or metal buckets. The packing can also be as per your order.

 

TIPS for your references:

1).how to choose the suitable grade( grade information)

As cold forging dies can be widely used in all industry, several grades are designed to perfectly meet all needs.
