What Is Composite Contract Manufacturing?
Composite contract manufacturing is the process of developing and manufacturing a product or composite component by a specialized manufacturer according to the technical requirements of the product owner.
This manufacturing model enables companies to bring products to market under their own brands without investing in their own production facilities, benefiting from experienced engineering teams, professional manufacturing infrastructure, and quality control processes.
Sterplas manages OEM composite manufacturing, composite part production, composite mold manufacturing, prototype production, and mass production under one roof.

OEM Composite Manufacturing
Sterplas provides OEM (Original Equipment Manufacturer) composite manufacturing services for companies operating in a wide range of industries.
Within our OEM composite manufacturing model, products can be manufactured:
-
To customer-specific dimensions
-
According to customer-defined technical specifications
-
In the desired colors
-
In line with your corporate brand identity
-
According to specific quality requirements
Depending on project requirements, custom branding, special surface finishes, and project-specific production details can also be integrated into the product.
Sterplas' OEM manufacturing approach goes beyond production by also covering engineering support, process management, and consistent quality assurance.
Which Industries Are Suitable for OEM Composite Manufacturing?
Our OEM composite manufacturing services are flexible enough to meet the needs of a wide range of industries.
The main industries we currently serve or for which we can develop customized solutions include:
-
Swimming Pool & Spa Systems
-
Automotive Industry
-
Commercial Vehicle Equipment
-
Marine & Boat Equipment
-
Construction & Infrastructure Projects
-

Defense & Specialized Industrial Projects
Each industry has different requirements regarding mechanical strength, chemical resistance, UV resistance, surface quality, and manufacturing standards.
For this reason, Sterplas evaluates every project with an engineering-focused approach rather than offering standard solutions, ensuring the most suitable composite manufacturing process for each application.
Advantages of Composite Materials
Composite materials offer significant advantages over traditional manufacturing materials in many applications.
High Strength
Glass fiber reinforced composite structures provide excellent mechanical strength despite their lightweight construction.
Design Flexibility
Advanced composite manufacturing technologies enable the production of complex geometries as a single integrated part.
Corrosion Resistance
Composite products do not rust and offer outstanding resistance to a wide range of chemicals.
Long Service Life
With the right material selection and high-quality manufacturing, composite products maintain their performance for many years.
Lightweight Structure
Composite products are significantly lighter than steel and many other conventional materials.
Low Maintenance Cost
Since they do not rust, rot, or suffer from surface degradation, composite products require minimal maintenance throughout their service life.
How Is the Most Suitable Material Selected for Your Project?
Not every composite product is manufactured using the same material system.
Sterplas' engineering team evaluates:
-
Application area
-
Mechanical load requirements
-
Operating temperature conditions
-
Chemical resistance requirements
-
UV exposure
-
Production volume
-
Cost targets
to determine the most suitable composite material system for each project.
This engineering-based approach ensures optimum solutions in terms of both technical performance and cost efficiency.
Composite Mold Manufacturing
At the core of every high-quality composite product is a composite mold that has been accurately designed and manufactured with high precision. Product dimensional accuracy, surface quality, production efficiency, and consistent quality in mass production all depend directly on the mold design.
At Sterplas, we manufacture custom composite molds for each project and manage the product development process with an engineering-driven approach. From one-off prototypes to high-volume mass production projects, we develop the most suitable mold solutions for different manufacturing scenarios.
Advantages of Composite Mold Manufacturing
-
High dimensional accuracy
-
Superior surface quality
-
Consistent quality in mass production
-
Shorter production times
-
Lower production costs
-
Long mold service life
-
Repeatable production quality
The most suitable mold system is determined after analyzing the intended application, production volume, and technical requirements of each project.
Depending on the project requirements, we manufacture:
-
Prototype molds
-
Low-volume production molds
-
Mass production molds
-
Multi-piece mold systems
-
Large-scale industrial molds
