How to Save Time and Money


Time is money.   This is never truer than when developing a new product.   Premold Corp’s approach to Reaction Injection Molding (RIM) and your project will save you both time and money in several ways:


Consult with us to reduce your design time.   Our Reaction Injection Molding (RIM) process can successfully produce thin and thick walls in the same part.   There is no need to spend valuable design and tooling time to core out complex areas of a molded plastic part.   Simply design the cosmetic and functional shapes you want and move on to other productive tasks!


With Premold Corp there’s seldom a need to spend time and money on expensive prototypes.   We specialize in Reaction Injection Molding (RIM) and have conducted dozens of seminars on Reaction Injection Molding (RIM).   When we agree to take on a project, we know it will be successful.   Our short tooling lead times give you more design time and faster “art to part” times.   Our low tooling costs reduce the financial risks of skipping the prototyping step.   A high percentage of our parts are approved after the first tool trial.   If design changes are required they can be made faster and at lower cost in our CNC machinable, epoxy or aluminum molds.   For very complex parts, we’ve perfected numerous techniques to quickly and economically fine-tune close tolerance dimensions.


Premold Corp’s low cost tooling options all require less lead time to prepare for production.   Our most basic molds are made without water lines and ejector systems.   This saves you time and money.   Even our long-life aluminum molds can be produced very quickly.   The low molding pressures and temperatures of our Reaction Injection Molding (RIM) process allow us to use fast machining mold materials.   All molds are CNC machined directly from customers’ CAD files.   This eliminates non-value added interim steps and ensures closer part tolerances.   Premold Corp’s molds typically cost 50%-75% less than high pressure injection molds.


Our ability to mold varying wall thicknesses in the same part minimizes your tooling costs by eliminating unnecessary coring.   In fact, our highly creative tooling and ease of molding complex parts frequently enables customers to combine two or three parts into one molded plastic part.   This saves you design and development time up front and procurement and assembly time later on.
