If you are a manufacturing company that is developing a new product that requires injection molding, then obviously looking for an injection molded plastics shop is your first step in getting the part created. However, if you are hung up on the fact that you aren’t sure exactly what you want, don’t let it stop you from contacting an plastic molding company.

The process in and of itself always involves custom molds, and most companies, therefore, have the capability to help create prototyping parts or proto mold that will suit your needs perfectly.

Plastic injection mould is machines created to follow through with the prototype design with perfection, and the process is very reliable. Mass […]

5 Axis CNC Machine for high precision plastic mold manufacturing

5 axis CNC machine is used in modern industry for not only reducing the production cost, but also it saves time and increase the profit and accuracy of the job. Actually, 5 axis CNC is most useful for complex machining. We will explain it later.5 Axis CNC Machine

The most number of CNC machine is operated under 3 axis movement which is X, Y, and Z. Those movements are mainly up-down, right-left side and front-back movement. Maximum simple machining operation is performed quite completely under these three movements.

But for some special type of machining (turbine impeller) or machining, a […]

Polymethyl Methacrylate (PMMA) Plastics Material

PMMA plastics is commonly known as polymethyl methacrylate, acrylic and so on and its chemical name is polymethyl methacrylate. PMMA plastic material has some defects such as low surface hardness, easy to snag, low impact resistance, poor molding liquidity performance.

So PMMA’s modification appears one after another such as copolymerization between methyl methacrylate and styrene and butadiene, a blend of PMMA and PC, etc. 372 PMMA is the copolymer of methyl methacrylate and styrene. If you add a small amount of nitrile rubber (about 50%) in the 372 PMMA, it will become 373 PMMA.PMMA injection molding parts

The fluidity of PMMA plastics is poorer than […]

How To Convert machined parts to molded parts

How To Convert machined parts to molded parts

Millions of plastic parts are machined.  If the annual volume is high enough, converting it to a molded part could be of advantage. With machining, you pay for the full rod or sheet and then machine a fair amount of the plastic onto the floor as waste. Extruded sheet and rod is usually more expensive per pound than injection molded pellets.  For example, if molded pellets are $5.00/lb. extruded rod of the same material will cost around $10.00/lb.  Then, you have the cost of machining on top.

Machined parts don’t just have to be plastic to become an injection molded part.  Many parts International Plastics produces were originally machined metal parts.  […]
