One of the ways that companies have been able to reduce lead times for new injection molds is to use quick change mold systems.  This typically means that there is a common mold frame that is stationary in the molding machine and the only part being constructed is the core and cavity inserts.  This system creates [...]

Draft and wall thickness are two of the most critical and overlooked fundamentals when manufacturing and designing for injection molding.DraftDraft is a design feature that involves tapering the side walls of a part to allow it to be released from the mold when the mold opens. Drafting walls in the direction of the mold helps [...]

What do a leather wallet and a ketchup bottle cap have in common? You got it…they both implement the living hinge to bring the object to life through movement. A living hinge is a thin flexible web of material that holds two rigid plastic pieces together. The living hinge concept has been around for years [...]

Proto-duction tooling, also known as ‘Prototype-to-Production” tooling is gaining momentun in today’s manufacturing world as people look to reduce capital costs of molds. This type of tooling is production steel multi-cavity tooling, with the 1stcavity being the prototype tool. When the 1stcavity is constructed, sampled, adjusted, and approved, then the remaining cavities are built to [...]

One of the fastest growing injection molding market segments is medical.  This is a coveted market by many because it seems to be relatively isolated from economic downturns.  One of the biggest tickets to entry for this market is cleanroom molding.  But many ask “What is cleanroom molding and what does that mean?”Let’s start with [...]

Polyvinyl Chloride (PVC) is the third most widely used thermoplastic behind Polyethylene and Polypropylene.  A large majority of the PVC is used for construction goods because it is inexpensive, durable and easy to use.  It also can be manufactured in both hard and softer durometers which enables it to be very versatile. Now that we see [...]

Plastics News had a great article in April on the use of aluminum injection molds for the automotive industry.  As the automotive industry goes through a major correction, it is forcing them to think differently about how they manufacture parts.  Honda of America is being very progressive in their thinking. Never before has an automotive manufacturing [...]

Recently, the use of Ultem material was made available to the engineering community through the Fused Deposition Modeling (FDM) additive manufacturing process.  This is a big step for product development because it starts to break down barriers many people have regarding the use of rapid prototyping before purchasing injection molds. The use of rapid prototyping to confirm designs [...]

As product life cycles shrink, it is starting to change the way people view injection mold tooling and parts.  In the past, aluminum molds were used primarily for prototype tooling and only a so called “fool” would use them for production.  Now, that is changing and changing fast.  With life cycles shrinking and the focus [...]
