Our Clients


Quality Systems

The Boneal Custom Molding (BCM) Quality Management System is designed to consistently provide product that meets customer requirements as well as applicable regulatory requirements. This system aims to enhance customer satisfaction through effective application of the system including processes for continual improvement and the assurance of conformity to customer requirements.


In house, we are have injection molding presses with capabilities ranging from 90-310 tons, as well as shot sized from 6.4-40 ounces. But through our many years of a strong network, we have build working partnerships with the ability to press up to 1,000 tons as well as 148 ounches of shot size capability.

We also regularly work with hot runner systems, complicated slide mechanisms that are required to produce complicated-part geometics. This is obtained through precisely controlling plastic melt and the cooling of the mold through regulation of water temperature and flow through the mold.


Mold Design & Build

With over 100 years of collective experience, Boneal Custom Molding will take your part design and develop and build the most cost effect tool to produce your parts.


Insert Building & Over Molding

We take pride in our ability to do close tolerance insert molding, which involves placing a core or “insert” into the mold and molding plastic around this part.

Cast Urethane

Manufactured using high-performance resins, curatives and additives, our cast urethane products can be manufactured in almost any hardness or shape.
