Bio-based Plastic Processing

In December of 2018, industry representatives were at Steinwall to observe the processing of four different bio-based filled resin made from the pulp of agave, rice hull, coconut, and maple wood. The representatives said, “Steinwall was the best bio-based plastic processor they have observed,” with regard to temperature and shear control of the plastic. Steinwall successfully processed the parts on their first attempt with these RheTech supplied resins. This was partially due to the collective […]

Uses for Plastic Injection Molding

Why do we use plastic injection molding? There are several reasons why many companies choose to use plastic injection molding. The most popular reasons include; the overall costs are lower, higher efficiency, and the ability to use multiple plastic types. Costs Are Lower Because it is an automated process, the majority of the plastic injection molding process is completed by robots and machines, which means only one person is necessary to control and manage them. Although the initial […]

Does Low Constant Pressure Injection Molding Work?

Jan H. Schut, Plastics Engineering It could be the most unusual new development in injection molding in the past 20 years, developed by household products giant Procter & Gamble Co., Cincinnati, OH (us.pg.com). According to P&G patents, the technology consists of retrofittable controls and software for aluminum injection molds with pressure sensors and special cooling, which P&G claims increase productivity more than 50% on existing injection molding machines. P&G set up a subsidiary, Imflux Inc. […]

Famous Engineers in History: Olive Dennis
