Product Description
Plastic injection moldingPlastic Injection molding is the most commonly used manufacturing process in large volume. Once the initial costs have been paid the price per unit during
injection molded manufacturing The price also tends to drop drastically as more parts are produced.
Injection Molding produces low scrap rates relative to traditional manufacturing processes like CNC machining which cut away substantial percentages of an original plastic block or sheet. This however can be a negative relative to additive manufacturing processes like 3D printing that have even lower scrap rates.
The advantages of plastic moldingA wide variety of products are manufactured using
plastic injection molding, it vary greatly in size, complexity, and application.
The injection molding requires an
injection molding machine, raw plastic material, and a mold. The plastic is melted in the injection molding machine and then injected into the mold, it cools and solidifies into the final part.
Injection Molding is very repeatable. That is, the second part you produce is going to be practically identical to the first one etc. This is a wonderful characteristic when trying to produce brand consistency and part reliability in high volume production
Plastic Injection molding is used to produce thin-walled plastic parts for a wide variety of applications, Plastic housing is a thin-walled enclosure which have many ribs and bosses. These housings are used in a variety of products including
household appliances, consumer electronics, power tools, and as automotive dashboards. Other common thin-walled products include different types of open containers, such as buckets.
Injection molding is also used to produce several everyday items such as
toothbrushes or small plastic toys. Many medical devices,
including valves and syringes, are manufactured using injection molding as well.
Note: waste plastic from injection molding manufacturing typically comes consistently from four areas: the sprue, the runners, the gate locations, and any overflow material that leaks out of the part cavity itself (a condition called "flash").
