Our Custom Manufacturing Solutions

Precision Injection Molding

Are tight tolerances, thin-walls, and complex geometries limiting your design flexibility? We utilize a unique combination of an extensive knowledge of ultra and high performance thermoplastic materials, mold flow analysis, a proprietary tool design system and process expertise to eliminate or minimize the need for secondary operations. If it’s possible to mold, we can do it. A bold statement, and one we take very seriously.

We make extensive use of technology to achieve exacting dimensional tolerances and overmold complex inserts.

Net Shape Molding

We augment the latest software tools including solid modeling (Solidworks, STP, Parisolid, and IGES), mold flow analysis and finite element analysis with an internally developed iterative tool design approach.  Our process incorporates 3D CT scan measurements of the internal and external geometries of highly complex parts.  This generates a component plot with up to 1.2 million critical dimensional measurements which we, using our proprietary true form sizing technology, integrate with CAD/CAM software allowing us to make exacting tool modifications.  This tooling modification process results in best-in-class part tolerances, particularly useful in molding mission-critical parts where dimensional attributes need to be extremely precise. Further, we use this approach to produce net shape-molded parts of exceptional quality eliminating, or significantly reducing, secondary machining operations resulting in material and process cost savings. Seals and valve bodies, in particular, benefit from the tight tolerance and smooth surface finish utilizing our proprietary process capable of attaining 0.0003″ tolerance.

Insert Molding

Insert molding is a process that places a component into the mold, either manually or by automation, before injecting the polymer into the mold.  The injection molded resin flows in and around the features of the insert forming a highly secure bond between the insert and the polymer. Pexco’s ability to insert mold is significantly more advanced than other injection molders.  We have developed tool designs, fixturing and robotic material placement techniques allowing us to overmold very delicate inserts commonly thought to be too thin or complicated to be accurately placed and consistently restrained in the mold.  In addition, we commonly utilize difficult to mold filled (graphite, glass, long and short glass fiber, carbon fiber, etc.) and unfilled high performance thermoplastic polymers.  These capabilities give engineers greater design flexibility to maximize component performance and reduce cost in developing next generation products.

Highly Engineered Thermoplastic Materials

We have an extensive history of injection molding filled and unfilled ultra and high-performance thermoplastics resins (PEEK, PFA, FEP, Torlon®, Ultem®, EXTEM®, etc.), and partnering with world-class polymer scientists and industry-leading material suppliers to develop unique custom resin formulations to address our customers needs.


A highly inert material compatible with most organic compounds, virtually impervious to chemical, enzyme and microbiological attack and stiffer than PTFE.


An injection moldable, highly inert material similar to FEP with good dielectric properties and are resistant to atmospheric degradation.

PAI Torlon®

A high-performance, high strength, high temperature (500°F max) polymer that is injection molded and oven “cured” to produce a thermoset polymer with excellent bearing properties.


Well suited for high temperature and wear applications, PEEK mechanical properties and a flexural modulus are among the highest of all plastic resins.

PPS Ryton®

An engineered thermoplastic with high-temperature resistance, chemical resistance, flowability, and dimensional stability.

PEI Ultem®

An amorphous material with exceptional strength and rigidity under long term heat exposure, with excellent impact strength, flame resistance and generates very low levels of smoke when burned.

Celazole® PBI

Unique and highly stable linear heterocyclic polymer.  PBI is an engineered thermoplastic that has exceptional characteristics such as high compressive strength, high modulus, low creep, and solubility in few solvents.


Unique and highly stable linear heterocyclic polymer.  PBI is an engineered thermoplastic that has exceptional characteristics such as high compressive strength, high modulus, low creep, and solubility in few solvents.

Nylon (Polyamide, Zytel®, Nylon 66)

Outstanding chemical resistance, even at elevated temperatures, resists most common organic compounds and is not attacked by water or pressurized steam.
