Moldtronics is a custom thermoplastic and thermoset plastic molding company.  Unlike other molders we mold both thermoplastics and thermoset materials.  This capability allows Moldtronics to offer the widest selection of materials to meet a given application.  This ability to work with a wide variety of materials combined with our totally internal mold building capability and 46 years of molding experience provide the tools required to take on any precision molding job.  

Cost and lead-time are important.  With our internal tool shop we can quote a project and get started while other molders are still in the quoting stage.  Email your IGS files (3D geometry) or  DWG (2D drawings) to us for a quote.

Thermoplastic Molding (also known as injection molding)	Insert Molding	Thermoset Molding
A thermoplastic polymer is one which melts or flows when heated. Thermoplastic polymers are usually not highly crosslinked, and act much like molecular solids: low melting and boiling points, high ductile strength.	Insert molding is the process of molding plastic around preformed metal inserts.  Moldtronics is a pioneer in the field, having produced some of the first parts using this process back in 1957.  This process is compatible with both thermoplastic and thermoset materials.	A thermoset polymer is one that doesn't melt when heated. Thermoset polymers "set" into a given shape when first made and afterwards do not flow or melt, but rather decompose upon heating. They are often highly crosslinked polymers, with properties similar to those of network covalent solids- i.e., hard and strong.
