Plating on plastics can be achieved with various metals. Copper is the obvious choice when there is a need to enhance the electrical conductivity of the substrate. Gold or silver plating plastic can also be used to add aesthetic appeal to a plastic product. Nickel plating on plastic is also a widely implemented metal finishing industry practice.It is possible to plate a variety of metals onto plas...

According to Global Market Insights, the automotive industry is still the predominant user of plastic on plating technology (79.2%), followed by domestic fittings (plumbing; 9.9%) and electrical/electronics (7.7%). Let’s take a look at some of the more common plastic plating applications in each of these industries.AutomotiveGlobal Market Insights indicates that polymers now account for approximat...

The increasing popularity of the use of plastics and plastic composites in a wide variety of manufacturing processes has also led to a greater demand for plating on plastic. Plating plastic with a metal surface enhances the appearance of the material and creates the impression of higher quality. As a result, it is often selected when a highly decorative look is desired.Additionally, plating on pla...

While the initial success of plating on plastic was achieved with ABS — in fact, ABS still comprises approximately 90 percent of all metal plating plastic applications. effective techniques have been developed for plating on a wide range of plastic materials. Many of these materials are classified as thermoplastics, which means they become moldable when heated above a certain temperature, and then...

In the “Plating on Plastics” process the bonding of the metal to polymer takes place at a molecular level, the quality and surface finish of the plastic moulding is extremely important as it will be reflected in the final product. Unwanted features such as “sink”, “flow lines” and “weld lines” become magnified by the high gloss surface of the plating. Defects in the polymer surface, such as “silve...

There are a number of design requirements for the successful moulding of electroplating plastic parts:Integral parts should be used to avoid welded or gluded jointsGates should be put in non-appearance areasRibs and Bosses should be designed to eliminate sink marksTexturing can be used to break up large flat surfaces and hide any defects such as scratchesDraft angles should be at least 1degree for...

Copper plating is done on polymer substrate to provide electrical conductivity and decorative coating. Nickel helps in providing wear resistance, enhancing corrosion resistance and increasing surface thickness. Chrome plated plastics offers advantages such as good surface finish, rust resistance and aesthetic appeal.

Types of Plastic That Can Be PlatedTo enable plating to adhere onto plastic, you need a special type of plastic. Generally, the type used is electroplating grade Acrylonitrile Butadiene Styrene (ABS). If you have plastics that are nylon or contain polycarbonate, please speak to a technical representative from Precision Plating.Plastic parts generally need to have purpose built racks. This is to en...

Warpage is usually caused by moulded-in stresses. The issue of warpage is related to being a semi crystalline material, HDPE, being semi crystalline polymer, will have differential shrinkage along and across the flow leading to warpage. It is difficult to eliminate this problem just by optimizing processing parameter. If use of multiple gates is possible, that might help multidirectional flow lead...

Injection moulding processing can affect shrinkage, but not as much as fillers. Increase shrinkage: shorter cooling time in injection mould. Higher mould temperature. Greater product thickness. Higher resin melt temperature during injection. More plasticizer in resin. Less injection speed. Lesser packing / holding pressure and volume. Decrease shrinkage: longer cooling time in the injection mould....

1. Company should keep a detail record of Mould Operation, including its usage, maintenance (lubrication, cleaning, rust protection) and damage. According to these, which components are damaged and the degree of wear will be found. These will offer information for discovering and solving problems, molding technological parameter, and product material, to shorten mould trail time and improve produc...

Injection molding is an engineering technology. It involves changing plastics into useful products with its original properties. The important process conditions for injection molding are the temperature, pressure and corresponding action time that affect plasticizing flow and cooling. A.Temperature Control1.Feed cylinder temperature:Temperatures that need be controlled during injection molding ar...

Plastic injection molding is extremely versatile method of producing plastic parts. It is one of the preferred methods for manufacturing plastic parts because it has multiple advantages over other methods of plastic molding. Not only is plastic injection molding simpler and more reliable, it is also extremely efficient. You should have no doubts about using this method to manufacture parts.1. Deta...

Understanding Plastic ExtrusionThe plastic extrusion process starts by placing raw resin into the extruder's hopper. Essential additives for the particular application (such as UV inhibitors, anti-oxidants, or colorants) are then added to the plastic extrusion equipment. Once in cast, the resin is usually gravity-fed through the feed throat of the hopper down into the extruder's barrel. Within the...
