Have you ever looked at the bottom of a plastic container and noticed one or more symbols molded into the part? These markings are added at the time of molding with a metal insert placed in the cavity of the mold. When the resin solidifies it bears the mark of the specific insert added. Believe it or not these markings can be extremely important and very helpful for molders and consumers alike as they guide decisions through the life cycle of the plastic part. For the molder, the markings provide key information which can include when the part was made, helping to identify a specific manufacturing lot or batch and ensuring that a reliable quality system exists. For consumers, the markings can show how the finished good can be used and possibly re-purposed through recycling.
High-Temperature Blind Hole Inserts
The use of engineering resins is increasing and since these resins are processed at elevated temperatures, high-temperature inserts are required. One important feature of high-temperature inserts is a blind hole which allows the mold designer to enhance cooling around the location of the insert.
Food Container Inserts
Fast-paced lifestyles and more affordable modern day conveniences, such as microwaves, and dishwashers for example, have changed the food container industry for both the manufacturer and the consumer. Food Container Inserts allow producers to easily identify the material characteristics of the product. These simple pictured images take the guess work out, allowing consumers to quickly visualize appropriate conditions for product use.
As we all know today, green initiatives have become common practice. More and more plastics are being recycled to avoid placement in landfills, ultimately protecting our environment. Through the use of recycling or resin identifier inserts by manufacturers, recyclers can easily sort and recycle post-consumer plastics helping the sustainability of our industry.
The Industry Innovator
The ability to effectively cool the mold is imperative for managing an efficient cycle time. Up until now mold inserts have been an incumbent as they often interfered with the location of the water lines used to cool the mold. Recognizing this gap in performance DME has introduced the first mold insert that is inserted through a blind hole. This added feature allows the mold designer to enhance cooling around the location of the insert and improve the molders productivity. It also eliminates the need to remove the mold when it is time to change the insert. This is a truly major industry breakthrough.
