Several Machining Ways of Kovar Alloy
Several ways of processing kovar alloy, Kangding Hardware personal experience tells you the pros and cons of various ways
Kovar alloy processing products are mainly used for glass sintering, so Kovar alloy parts are mainly based on cavity structure. That is to say, the parts and products generally have an internal space for placing the electronic structural parts and then sealing the glass.
CNC machining and CNC core-moving machine are two main processing methods for Kovar alloy parts. CNC machining of Kovar alloy is mainly aimed at the production of quadrangular cavity structure parts. NC core-walking machine is mainly used to process Kovar alloy for cylindrical cavity structure parts. CNC processing and CNC core-moving machine processing are generally referred to as machine processing. The Kovar alloy material has a relatively high plasticity, so it is easy to stick a knife when processing the kovar alloy. Especially for Kovar alloy drilling and tapping, it is particularly easy to break the tool due to the sticking knife, so the processing efficiency is not high. In addition, when processing the cavity, a large number of materials will be excavated to form space, so the material utilization rate of Kovar alloy parts is not high, generally less than 50%. These are the drawbacks of Kovar alloy machining. However, if the customer orders for Kovar alloy products are small, machining is also the only more convenient processing method.
Kangding Hardware has encountered several customers who are in high demand for kovar customers. Kangding Hardware met several customers who were in great demand for Kovar alloys. Because the speed of machining can not keep up with the needs of customers, Kangding Hardware is forced to choose other processing methods, and now share them with you in order to make common progress.
In 2018, I received a Korean customer who needed 50,000 Kovar products per month. The product is a hollow product with a length, width and height of 30*15*10mm and a wall thickness of 1mm. If CNC machining is used, one is that the output does not meet the customer's demand, and the other is that the cost cannot meet the customer's demand.
Kangding Hardware has also looked for a powder metallurgy process, but it cannot be used because of the high nickel content of the Kovar alloy. Later, Kangding Hardware Group so R&D personnel tackled the key problem and came up with the Kovar alloy strip material with stretching technology to make the cavity.
Through the actual inspection, it fully meets the requirements of the guests, and the mass production speed and cost unit price can also meet the requirements of the guests, and the problem is solved satisfactorily.
There is also a Kovar alloy processing cavity, the shape is relatively ordinary, like matchbox, three sides require hollowing, this kind of stretching method can not be completed. It must be done by extrusion with a press of more than 300 tons. Kangding Hardware is still very experienced in the extrusion of Kovar. But this kind of cavity open continuous cold extrusion die is relatively expensive, usually more than 70-80,000 RMB, so you do not have more than 200,000 orders for Kovar alloy parts or need not consider.
