Dupont Vespel PI Polyimide nuts Manufacturers

PPSU is a slightly amber linear polymer. In addition to strong polar solvents, concentrated nitric acid and sulfuric acid, it is stable to general acids, alkalis, salts, alcohols, and aliphatic hydrocarbons. Partly soluble in ester ketones and aromatic hydrocarbons, soluble in halocarbons and DM. Good rigidity and toughness, temperature resistance, heat oxidation resistance, excellent creep resistance, corrosion resistance of inorganic acids, alkalis, salt solutions, ion radiation resistance, non-toxic, good insulation and self-extinguishing, easy to mold and process.

CNC precision machining is actually exponential control machining, first write the design drawings into the program, and then connect the computer to the CNC machine tool, control the operation of the CNC machine tool through programming, complete the processing of precision workpieces, CNC precision machining is mainly suitable for small batches, a variety of workpieces processing, precision machining, the material it uses, are strict requirements, not all materials are suitable.

It is possible to CNC mill plastic. Actually, one common method for producing plastic parts fast, precisely, and with a high level of precision is CNC machining.

The cooling time of the part usually refers to the period of time from when the plastic melt fills the cavity of the injection mold until the part can be opened and taken out. The time standard for taking out the part by opening the mold is often based on the part that has been fully cured, has a certain strength and rigidity, and will not be deformed and cracked when the mold is opened and ejected.

There are many reasons for the sticking and poor demoulding of injection molding products, and mold failure is one of the main reasons. The causes and treatment methods are as follows:
