Custom Molding

For over 50 years, Rebling has been manufacturing custom-molded plastic parts for its Customers in the Instrumentation, Medical, Consumer Products, Defense, Industrial Equipment, Energy, Avionics, Communications, Pharmaceutical, and Transportation industries. If you are in need of a manufacturer with expertise in custom molded parts applications, we encourage you to read on and learn why our customers trust us to deliver.

The parts we’ve manufactured in custom plastic molding projects range from dime-sized to gallon-sized, from parts designed to last 50 years to those designed as disposables, in quantities from 500 pieces to 20,000,000 pieces per year and for environments as pleasant as an air conditioned office to as unforgiving as an oil drilling borehole. No matter the custom plastic molding requirements, we have probably done it before.

We produce thermoplastic and thermoset custom molded parts using hundreds of different standard and custom plastic formulations (see alphabetical listing below) and offer a wide spectrum of insert-molding (plastic molded around metal parts), over-molding (plastic molded around plastic parts) and post-molding services (machining, assembly, printing, laser marking, ultrasonic welding, heat staking, etc). We specialize in a wide spectrum of molding services, including insert molding and over-molding services. 95% of the parts we produce are smaller in size than a gallon jug of milk, weigh less than one pound and have a maximum dimension shorter than 12 inches.

Whether you have a drawing, a sample or simply an idea, our team can design the part and select the material which best fits your needs, perform 3D modeling, create full size prototypes, design and create the mold, perform first article inspection then produce production quantities. We are ITAR registered and ISO 9001 certified.

Here’s an alphabetical listing of some of the plastic compounds we use in our custom molding services. We have the unique ability to mold heat resistant thermoplastics (those with a high thermal index). Thermoset compounds are marked with an asterisk. Detailed explanations which further differentiate these plastics can be found in our Materials section.
