How to identify the quality level of the recycled plastics materials

1. The glossiness of surface is an important indicator to measure the quality level of particles of all kinds of recycled materials. Recycled materials of good quality have glabrous and smooth surface.

2. Transparency is also an important indicator to measure the quality level of particles of middle and high-grade recycled materials. Materials with the good transparency are usually of good quality.

3. The uniformity and consistency of color is an important indicator to measure the quality level of particles of colored recycled materials. For example: white, creamy white, yellow, blue, black and other colors

4. The density of particles is an important aspect to inspect the level of the regeneration process. 
Poor plasticizing and loose particles

5. To test whether the recycled particles sinking water or not can be used for inspecting the stuffing content of PP and PE.

As for recycled materials, different recycled materials have different applications, as there’re no uniform standards and it is also difficult to institute it. The only standard if have to say is to well meet production requirements of the users.

3D CAD design for plastic injection molding

Over the years, 3D CAD systems such as SolidWorks have become more and more integrated into the design and manufacturing processes. Plastic injection molding is no exception. Industrial designers use 3D CAD to make ergonomic and aesthetic contours which would be next to impossible to communicate in 2D drawings. Modern toolmakers must use 3D models to make the mold cavities. Also, most rapid prototyping machines accept only 3D files to create parts.

Rebling Plastics has extensive experience using SolidWorks and CADKEY to design parts for plastic injection molding. While formats are constantly changing, we have successfully imported from and exported to virtually all other CAD programs, including Pro/ENGINEER, CATIA, Solid Edge, Inventor, and AutoDesk/AutoCAD. In addition, we use universal formats such as IGES, STEP, DXF, DWG, parasolid (x_t), STL, and many others.
