The conventional injection molding process manufactures products that meet diverse industry needs. But some products need some modifications to the conventional injection molding process. This could be to achieve a more complex design or to make the production process more efficient. Such advancement could result in significant cost reduction and time-saving.  2 shot injection molding is one of such advances in conventional injection molding. It is adaptable to the production of complex designs using a wide range of materials. 2 shot injection molding achieves high quality of products. It is a well-established technology in the manufacturing industry.  A description of

Thin wall molding is gaining popularity due to its lower material cost and high production output. A thin wall refers to an electronic part that has a wall thickness of less than 1mm. For large size parts, the thickness can increase to some extent as 2mm. Injection molding maximum wall thickness for large parts may be 2mm to 4mm. Thin wall plastic parts rely on the thickness of parts. Flow length for thickness ratio and velocity also affects the thickness of the wall. We can make changes in wall thickness with: Fast Cooling Time High Speed And Pressure Part Ejection

Nylon66 or PA66 as it is also known as polyamide. Polyamides are a class of polymers which are thermoplastics.  characterized by the amide group in their repeating unit. They find use in many applications. The 6,6 here relates to the two structural units that make the repeating unit. It comprises a carboxylic acid and amine compound with 6 carbons each. PA66’s repeating unit is a combination of hexamethylene diamine and adipic acid. There are several other forms of nylon with a varying number of carbons. All have different properties so these numbers are important. They distinguish the different types of

In trying to manufacture good quality plastic gears. Processors must face some challenges. We’ll discuss these challenges and how to solve them. First, let us look at why even bother with plastic gears in the first place.

Glass fibers combine the properties of glass with those of plastics.  This makes injection molding possible. But the injection molding of glass fibers is quite different from that of plastics. In this article, you’ll learn about glass fibers and how they are injection molded.  The injection molding of glass fiber is an interesting area. Glass fibers have transformed the processing and application of glass. It has done the same for plastics. The field of glass molding may seem to have lost a lot of attention to plastics in the past years. Today plastics such as polycarbonate and PMMA have replaced

Now more than ever, manufacturers have more choice of plastics. Likewise, the possibilities of products made with plastics are endless. Consumer goods, vehicle parts machines, cosmetics food, healthcare, and more. Plastics seem to have found their way into all areas of our lives. Many of us are aware of the 7 recycle signs. Those are only a small fraction of the number of plastics that exist. The plastic number 7 which indicates “other” contains more types of plastics than 1 to 6 put together. Nylons, polymethyl methacrylates, polyurethanes, acetyl butyl styrene, polyvinyl acetate, polyacrylonitrile. These are some examples of other

ABS is a thermoplastic polymer. It has an amorphous structure and melts temperature between 190 and 270oC. But it is injection molded between 40 and 80oC. A terpolymer of acrylonitrile, butadiene, and styrene produced by emulsion polymerization. It is a low cost, high impact resistant, and lightweight. It has an average density of 1.07g/m3. It can withstand an impact of 200 -215J/m. ABS is a low-cost material.
