In some cases, products will bear heavy loading, or there are certain defects on the surface, or there is residual stress, or cannot meet the engineering design requirements; we can have shot peening, pressure, rolling and other methods to improve the surface of the product emphasis. By those methods,...

Laser marking application on prototypes Laser engraving or laser marking, is based on numerical control technology, laser as the processing media. The physical denaturation of instantaneous melting and gasification of processed materials under laser engraving irradiation can make laser engraving...

What are the main differences between vacuum plating and water plating for plastic products? 1.Processing technology is different: -Water electroplating, is related to water and aqueous solution, the principle of electrochemical reaction, is a chemical process. Pollution is high due to heavy use...

One quick understanding of paining process on prototypes Usually the whole painting including 3 steps, Primer: The purpose is to fill out the some dents or pits, improve the adhesion as well as defect indication. Intermediate coat: It’s very important and it’s one preparation for the surface...

Physical Vapor Deposition (PVD) refers to the film preparation technology of material deposition on the plated work-piece by physical method under vacuum condition. PVD technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating and vacuum ion coating....

Sheet metal material expansion size calculation The expansion drawing is the plan (2D) that is developed according to the part drawing (3D). Note the following during the expansion process, The way of development should be reasonable, and it is convenient to save materials and have proper process...

Vacuum heat treatment application in prototyping industry  Vacuum heat treatment technology is a new heat treatment technology developed in recent years. It can prevent heating oxidation and non-decarburization of products, vacuum degassing or degassing, eliminate hydrogen embrittlement, and thus...

What are the electroplating quality requirements of prototypes? Electroplating usually refers to the salt solution containing metal, to be plated substrate metal as the cathode, through electrolysis, so that the metal partials in the solution deposition on the substrate metal surface and format one...

What is Rapid Prototyping Technology? Some customers in the prototyping industry will ask, why many hand factories are called rapid prototyping company, what is the meaning of this rapid prototyping? In fact, RAPID PROTOTYPING technology, also known as RAPID PROTOTYPING MANUFACTURING (RPM) technology,...

Machine vibration and cutter flutter will result in work-piece surface chatter, high rate of rework, reject rate.The reason for machine tool vibration is generally the machine, work-piece, cutting tool in any one or more of the three systems of rigidity is insufficient, the following is the start...
