Abstract

According to the machining technology of the pneumatic connector, the pneumatic connector comprises a metal pressing piece, and the machining technology is characterized by comprising the following steps that metal raw material powder and a binding agent are kneaded to prepare master batches for standby application; s2, performing injection molding on the master batch prepared in the step S1 by using an injection machine to prepare a blank; carrying out thermal degreasing on the prepared blank; sintering the degreased blank to obtain a blank; injecting reaction type silica gel on the surface of the blank, and curing; wherein in the step S2, the temperature of a nozzle of an injection machine is set to be 150-200 DEG C, and the injection pressure is set to be 90-100 MPa; the reaction type silica gel is injected by adopting an injection machine which is the same as that in the step S2, and the curing temperature is 110-130 DEG C.

Description

technical field [0001] The invention relates to a processing technology of a pneumatic joint. Background technique [0002] The powder metallurgy process is a new type of net near forming technology. The required mold forming is performed by melting, heating, injecting and pressing metal powder. For some special materials such as refractory, refractory metals and high alloying, the traditional processing method It is difficult to be competent, and powder metallurgy has become the main processing and production method, especially in high-precision gears and auto parts. [0003] Metal Injection Molding (MIM) is a new type of powder metallurgy near-net forming technology derived from the plastic injection molding industry. It is well known that plastic injection molding technology produces various complex shapes at low prices, but plastic The strength of the product is not high. In order to improve its performance, metal or ceramic powder can be added to the plastic to obtain ...
