State-Of-The-Art Equipment

Our facility supports projects of all sizes and is equipped with a variety of advanced molding presses.

Material
Expertise

Our in-depth knowledge of composite materials helps identify the most suitable raw materials for your product.

Repeatable Uniformity

High quality assurance measures ensure uniformity across high volume production.

Beyond the ease of design and production, compression molded parts boast a higher strength to weight ratio than steel and outperform traditional materials in every way.

As experts in compression molding, Comoldco is able to offer you the very best in SMC, GMT and BMC Molding.

SMC Molding

The introduction of SMC (sheet molding compound) created a vast shift as companies chose to move away from metals and start using polymers.

SMC compression molding provides lightweight, durable and highly detailed products, at a fraction of the cost. Its lightweight and resistance to high-impact speeds are just a couple of reasons why so many of the world’s most notable vehicle brands now rely on SMC molding.

An added benefit of SMC molding is high production volumes in short time periods, all with exact precision and accuracy thanks to our custom molds.

SMC compression molding further saves time as they can be primed in mold, eliminating waiting times.

Examples of products that can be made with SMC compression molding include:

Auto parts
Baths/spas
Seating for arenas, cinemas, stadiums and even transit
Our proprietary line of anti-slip stair treads, ComposiGrip.
Detectable Warning tiles

Benefits of SMC compression molding include:

Reduction in weight, cost, wait times and waste
Non-corrosive
Impact resistant
Heat and noise attenuation

GMT Molding

Similar to SMC molding, glass mat thermoplastics (GMT) are ideal for creating lightweight and durable product parts, most commonly used in the automotive and building and construction industries. The material is heated prior to molding which decreases the time it takes to form into the shape of the mold. GMT molding offers manufacturing flexibility and can incorporate a decorative or function surface laminated to one side of the raw material. For high production of one part design, GMT is the most desirable choice.

Examples of products that can be made with GMT compression molding include:

Auto parts
Marine Parts
Electrical Components
Concert Speakers

Benefits of GMT compression molding include:

Increased stiffness, strength and durability
Complex parts can be molded in shorter periods of time
Ideal for large parts
Works well under very high pressures
High production efficiency
Non-corrosive and resistant to heat and impact.

BMC Molding

Bulk molding compounds (BMC), which is an unformed material mixture of resin FRP, can be used in compression molding as well as injection and transfer molding, making it a highly versatile material. Compression molding of BMC allows for tight dimensional control and creates a high-strength end-product that is flam resistant and boasts high color stability.

Examples of products that can be made with BMC compression molding include:

Electrical components
Institutional furniture
Auto parts

Benefits of BMC molding include:

Increased life span over traditional materials
High UV and color stability
Available in a wide variety of colors
High strength
Corrosion resistant
