Abs Plastic Injection Molding


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.

What Is Insert Moulding, And How Can You Know Insert Moulding Is Better For Your Production?

Like many people, do you want to know what insert molding is? And how is it different from other plastic injection molding processes?   For getting your answer, you must know all about insert molding and what insert molding is? It’s a process of molding thermoplastic material for creating a finished product. In a single molding part, we insert molded metals and plastic. We can also use many materials and metals for molding together into the same molding part or cavity. A component may be a single object as a surgical tube or knife. Which Industries are Using the Insert Moulding

Back Pressure Injection Molding


The concept of backpressure is interesting. This in part because it is an elegant demonstration of thermodynamics. One of many such in the injection molding process. It is one that is often overlooked. You’ll often find descriptions of injection molding with no mention of backpressure. In the fundamental sense, it relates the pressure exerted on the system to the screw motion. But beyond this, it also affects several other aspects of the process. Injection molding is an interplay of different events culminating in a formed product. Several parameters need control and are monitored in the process. Many of these parameters

Pvc Pipe Injection Molding 1


When it comes to pipes, PVC is the first word that comes to most people’s minds these days. PVC pipes have been in use for over 50 years since their first manufacture. Plastics offer several advantages over metal pipes. They are lightweight, they do not rust, and are better insulators. The fact that they get processed at a much lower temperature than metals makes them cheaper. They are long-lasting and hardly need replacement during their useful life. PVC pipes are the first choice for plastic pipes and fittings. The most practical method for producing pipe fittings is injection molding. Manufacturing

Clear Plastic Injection Molding


In many ways, plastics have replaced glass in several applications. Think display structures, sample bottles, tool parts, cosmetics containers, and Tupperwares. These amongst many others are examples of applications of clear injection molded parts. Clients want clear parts for different reasons. This could be to make the product more visible to customers. Some equipment parts need to be clear for functionality or aesthetics. For a while, glass has been the go-to for clear objects. They are durable, unreactive, and inexpensive. The primary raw material for glass is silicon dioxide, sand. A very abundant resource on earth. But glass comes with

Injection Molding Of Peek


Polymers have replaced metals in many applications in the medical and other industries. This has led to improved treatment and management of several medical conditions. While the field is expanding, there are some polymers with well-established applications. Polyether ether ketone, or PEEK, is one such. It is biocompatible, sterilizable, and durable. It finds use in applications ranging from tissue replacement to medical tools. PEEK is a high-performance polymer. Beyond the medical industry, PEEK also finds use in more complex applications. An example is the fabrication of aerospace and machinery parts. Injection molding of PEEK extends its applications to more complex

Overmold Illustration


If you are always curious about how things get made, at some point you would have taken a look at a plastic product. You would have wondered how it’s made. For those with some knowledge of plastic processing techniques, some might be obvious. Looking at a simple straight pipe one would immediately think of extrusion. A screw cap of a water bottle is most likely injection molded. You might have a product you want to manufacture. Could be that the design doesn’t quite fit into any of the typical processes. In such a case, you’ll need to use a combination

Disadvantages Of Injection Molding 1

Disadvantages Of Injection Moulding

There are some disadvantages of injection moulding. Not Fit For Low Volume This method is suitable for large production volumes. It’s an ideal process for large production. It’s not good for small productions. For small quantities and low volume articles, plastic prototyping techniques are the best. You can get your products in less time with this method. Due to the tools required and the testing; upfront cost is high. You get your parts after a long setup. It has a long process for making products. So the cost of injection moulding is higher than other methods. It makes the design

Vertical Injection Molding 2


Vertical injection molding works on the same fundamental principles as conventional injection molding. The simple variation in orientation makes a huge difference in the manufacturing process. Many manufacturers understand that every little matter when it comes to efficiency. In this article, we look at the features of vertical injection molding machines.  With a focus on the ones which make them better for some applications. In doing so we also look at why they might not be so good for some applications. You’d of course want to know if vertical injection molding works for your intended product. We explore some examples

Advantages Of Injection Moulding 2

Advantages Of Injection Moulding

Injection moulding is a prime method used for producing large numbers of articles. This method gets the advantage over other manufacturing methods. It has a tough geometry, product consistency, and low labour cost for making similar items. We inject molten plastics at high volume into a mould to create shapes and articles. You can get many materials such as a bottle cap, pocket comb, car panels, and mechanical parts. The injection moulding process has become a utilised strategy. The reason is its merit and extra benefits that it offers. It’s performed with other materials like elastomers, metals, glasses, and polymer.
