Near-Infrared (NIR) sensor technology coupled with highly sensitive algorithms are likely the most efficient and consistent plastic sorting technologies due to their high sorting accuracy in separating desired plastics from mixed waste, as well as sorting plastics by color and resin types. Identification algorithms then rapidly categorize the different “signatures” of polymers from their infrared spectra.

While other sensor based sorting technologies, such as x-ray, laser, and light e...

Plastic pallets are available in a wide variety. You need to know how much weight you are putting on a pallet and how it will be used and handled to select the proper type of pallet for your application. When looking at what you are putting on the pallet, capacities are based on evenly distributed loads. If you are putting coils or bags of product, the weight is not evenly distributed. The following should help a bit in explaining the different plastic pallet designs available.

Multi-Purpose...

In recent days there are plenty of cosmetics existing in the ordinary life around us. Women even men see cosmetics as important; and choose right cosmetic containers for cosmetic products is also important. It is offered by the cosmetic packaging industry that an extensive custom product completes design capability.  

Molds are built through two main methods: standard machining and EDM. Standard machining, in its conventional form, has historically been the method of building injection molds. With technological development, CNC machining became the predominant means of making more complex injection molding with more accurate mold details in less time than traditional methods.

More complex parts are formed using more complex molds. These may have sections called slides, that move into a cavity perpendicula...

The injection mold machine was relatively simple compared to machines in use today: it worked like a large hypodermic needle, using a plunger to inject plastic through a heated cylinder into a mold. The industry progressed slowly over the years, producing products such as collar stays, buttons, and hair combs.

The injection mold remains cold so the plastic solidifies almost as soon as the mold is filled. Two-shot or multi-shot molds are designed to "overmold" within a single molding cycle an...
