“Rex Plastics was very helpful in the product development process. They helped me with part design, material selection and made many improvements to the sample product I originally brought them. In fact, the design changes their engineer suggested literally cut the injection mold cost in half.” says Tom Arnold, owner of Powder Cord Pouch.
Rex Plastics Product Development Plastic Part Design Fundamentals Sink and Warp Plastic Part Design – What is Sink? Part manufacturers should always give careful consideration to the materials used in plastic part design, as this decision will have significant consequence in the sink & warp of plastic injection molded parts. Why is this? During the […]
Rex Plastics Product Development Plastic Part Design Fundamentals Draft Angle In this edition of our Product Development series, we’ll briefly overview a fundamental concept for plastic part design, ‘draft angle’. Draft angle, or ‘draft’ is essential for all plastic injection molded products. It facilitates the removal of the part from the mold. Adding draft […]
Rex Plastics Product Development Plastic Part Design Fundamentals Injection Molding Plastic design is the building block of plastics manufacturing, and can make or break not only the initial investment required to get a product launched, but the long term profitability of that product. In this series we will discuss the fundamentals of this very important […]
Custom plastic products are an integral part of this Country’s economic development and recovery. There is no more versatile material on the planet for use in electronics, medical, automotive, defense, consumer products, toys, and the list goes on. The inventors and entrepreneurs this country generates are well served by considering plastics for a broad range of applications.
According to Trade and Industry magazine, more companies are considering TCO to determine where to source their injection molders. A recent survey showed that 60 percent of respondents underestimated approximately 20% of their off-shoring costs. This realization has fueled better analysis of these costs, helping decision makers understand the difference between price and cost. This trend […]
At least to some degree, asking what plastic injection molds cost is a lot like asking “How much is a car?”. Will your mold be a Pinto or a Porsche? The determining factors in the cost of your mold are a combination of the part size, complexity, material, and anticipated quantities. For instance, if you […]
Custom injection molding is among the least expensive processes available for producing large quantities of parts. Due to the initial investment of the mold however, there is a return on investment that needs to be considered when making the decision on what type of process to use. If you anticipate needing tens or perhaps even […]
Finally there is a green alternative for producing plastic parts. Biopolymers are the green alternative using biologically derived polymers. These are an alternative to petroleum based polymers. Going green and corporate responsibility is growing interest by many companies. The growing world populations with limited natural resources has fueled a new type of renewable plastics… one […]
While a change to a product after launch can be quite expensive, making changes during the design stage is relatively inexpensive. Plastic part design is no exception. With today’s CAD software, being able to visualize, test, and change designs has never been easier. The Cost […]
