Why We Do Plating for Plastic Machined Parts?
Compared to the metal finishing process, in fact, we also can do the plating for plastic machined parts, such as spraying, electroplating, UV, and more. When we have produced many more plastic parts, in order to make better appearance and requirements, our customers usually also asked to make the parts better and aesthetic, since the grade of the plastic part is not good enough, so we need to do more plating to enhance its level. Today, we will take this blog to share some of the information on plating information for plastic machined parts.
Our plating of plastic products can’t only achieve good metal texture, but also it has much more advantage including the material weight is lighter than metal parts, while effectively improve the plastic appearance and decorative, also improve its electricity, heat and corrosion-resistant performance. we need to comprehensively consider the machining performance of the material, mechanical properties, material costs, plating cost, and its difficulty and dimension precision of the materials.
What are plastic parts plating and its purpose?
The plastic parts plating meanings that we will do coating for plastic machined parts such as springs, electroplating processes, in order to make the products surface better and aesthetic. Most of these finishing process for plastic parts we do coating which is similar to our metal parts finishing,
The purpose of plastic parts plating is in order to make their surface aesthetic and protective layer. This not only increases the appearance of the plastic, but also compensates for the defects of plastic, and endows the nature of metal, and gives full play to the characteristics of plastic than metal. And for now, there are a large number of plastic plating parts used in electronics, automotive, household appliances, and other industries. So the plastic plating process is very widely used to many industries.
Advantages and disadvantages of the plating for plastic machined parts:
- Easy to machining processing
- Good corrosion resistance
- Good electrical insulation
- Low price and mass production
- Poor weather resistance, easy to be exposed to light and brittle
- Poor heat resistance
- Low mechanical strength
- Poor wear resistance
- High bibulous rate
How to Choice better plating for your plastic machined parts?
How to Choice better plating for your plastic machined parts? We will take one existing example for you.
We have Israel customer who has an electronic project, In rapid prototype status, we have machined it with solid ABS material and aluminum material, and solid ABS material thickness is 6mm, so the whole project is heavy after completed the plastic machined parts and aluminum parts, we have painting common oil to the product, so looks like that whole product is very good quality, high level.
However, after prototype ready and completed, they have to move forward the production. To compare all of the statuses and in order to reduce the cost, they have decided to use injection mold for their product, the plastic thickness is 2mm, so when we have built the mold, and assemble 1st shot product, whole product level is not so good, looks like very common.
In order to increase the product level, we have suggested using rubber coating to the product surface, if so, whole product grade is very good, high standard, In fact, before using injection mold, we have suggested using extrusion tooling with aluminum material to product, but the cost is high, Finally, the customers have asked to use plastic injection molding, and use rubber coating to the product, whole product cost and grade are still very good. if so, we have well understood that the plastic plating process is very important to our industries.
With the rapid development of industry, the application of plastic electroplating is becoming more and more widely, becoming one of the important means of surface decoration in plastic products. At present, many people have started to plate on the surface of ABS, PS, PC, Nylon, etc. Especially in ABS plastic plating, the most widely used plating effect is best.
