Your Complete Source for Custom Molding, Product Development, and Engineering Services


Lomont Molding, LLC is a premier plastic molder offering complete in-house services including engineering, tooling, in-mold technologies and decorating, quality assurance, and assembly and secondary operations. We have been in business since 1982 and process various types of thermoplastic resins in our state-of-the-art manufacturing facility.

Custom Injection Molding

Our high pressure plastic injection molding  process is ISO 9001 Certified and is suitable for molding a wide range of materials. Injection molding is a low-waste, low-cost process that is suitable for production runs of any size, and the final product typically requires little to no finishing.


Extrusion is used to create plastic products with a continuous cross-section such as pipes and decorative molding. Plastic extrusion uses raw thermoplastic beads that can be enhanced with custom colors and UV inhibitors, and is a versatile molding process that is inexpensive and can be used for a wide range of applications.

Structural Foam

Structural Foam Molding is used to create lightweight molded parts with dimensional stability and strength-to-weight performance. Structural Foam Molding can reduce molding costs and conserve raw materials and works for parts of all sizes but is ideal for large parts, particularly those that require thicker walls.

Secondary and Assembly Services

Lomont provides secondary operations and assembly services to prepare your product for distribution including: painting, shielding, balancing, date coding, labeling, post-production bending, part assembly and packaging.

Manufacturing Services

Lomont’s Manufacturing Services are focused on delivering quality products and development utilizing the latest technologies in CAD software. We can assist with all stages of product and tooling development and offer services to help you reduce tooling costs and lead times. 

Blow Molding

Blow Molding involves inflating hot thermoplastic inside a closed mold, and is used to produce hollow plastic parts. Our Blow Molding capabilities include stretch blow molding, injection blow molding, and extrusion blow molding. We utilize a wide range of thermoplastic raw materials for the molding process.


Over-Molding utilizes heat and pressure, which allows Lomont to mold two materials together. We offer Over Molding services that are utilized for a range of applications including electronic devices, medical devices, automotive components, appliances, and others. Over-Molding is available for various material types.

Gas-Assist Injection Molding

The Gas Assist Injection Molding process uses nitrogen gas to create lightweight plastic products that have a superior surface appearance. Since the gas disperses evenly throughout the mold, the process can be used to create thin-walled parts that can be formed to a high standard of flatness without sacrificing strength and durability.

Lomont Molding is a diverse company where people are the foundation. As a company, we reject discrimination. Anyone who knows our company, knows this. We value our customers, suppliers, employees, along with our communities where we are actively engaged.
