All the products must be inspected strictly with the ultrasonic and only those haven't any harm such as pore can be shipped out. High density, high wear & impact resistance, which lead them a long lifetime.
How to ensure the high quality standard?
Do you want to know the details?
Please follow......
1, Soon after the order is confirmed, carbide forging die products will start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine
2, Before mass production, we need to do a trial pressing and sintering using every mould, and we check the appearances and the sizes of carbide forging die samples with micrometer, projectors etc. to ensure that the requirements of the drawings can be met before batch production
3, Bulk production ,press the raw materials to shape blanks,and all carbide forging die blanks must be passed by semi finished inspection,
4, Then sinter blanks to finish (HIP) and finished products inspection, we have 10 sets of vacuum sintering furnace and 2 sets of HIP in the factory ensure the best quality and production capacity.
5, 1). cleaning/tumbling is to make the carbide forging die look more beautiful.
2).The carbide forging die can be ground according to customers’ order to a tolerance of +/-0.05
