Background and Material Evolution of Construction Machinery Housings

As the construction machinery industry demands lighter structures, energy optimization, and integrated aesthetics, traditional metal housings are gradually being replaced by high-performance composite solutions. Heavy equipment composite housings, SMC molded housings, and FRP composite bodies are now widely used on excavators, cranes, pavers, and mining trucks.

With stricter environmental regulations and upgraded customer requirements, the industry is undergoing deep structural optimization. Sanse actively responds to these trends, launching a range of high-performance molded composite housings for tractors, excavators, forklifts, and more, helping clients achieve both lightweight and high-durability objectives. By using Sheet Molding Compound (SMC), Fiberglass Reinforced Plastic (FRP), and carbon fiber composites, companies can reduce the weight of construction machinery housings by 30–50% while enhancing corrosion resistance, impact strength, and extending overall equipment lifespan.

Composite Housing Molding: Efficient Forming Technology for Structural Upgrades

In composite forming processes, compression molding is the key method for achieving complex shapes and high-volume production. Sanse's proprietary construction machinery housing molding technology offers integrated body manufacturing solutions for clients.

Molding Process Overview:

• Material Preparation: Select SMC or BMC, cut to size, and preheat
• Die Heating: Preheat high-precision composite molds to 130–160°C
• Compression Molding: Apply high-tonnage press to ensure uniform thickness
• Cooling & Demolding: Cool, demold, trim, and finish for a smooth surface

Compared to traditional metal processes, composite compression molding greatly improves production efficiency and surface quality, particularly suited for batch production of operator cabins, engine hoods, side panels, and other housing parts.

Innovative Composite Applications in Construction Machinery

In harsh and variable operating environments, machinery needs both structural stability and easy maintenance. Sanse's advanced molding and composite solutions are widely applied to components such as tractor engine hoods, excavator housings, and forklift bodies.

Tractor Engine Hoods: Strength and Lightweight Combined

Traditional metal hoods corrode and deform under harsh conditions. SMC or FRP composite tractor engine hoods offer excellent weather resistance and impact strength, significantly extending service life and reducing vehicle weight to improve fuel economy.

Excavator Housings: Ideal for Extreme Conditions

Excavator housings often face high temperatures, sand, and moisture. Sanse's high-strength composite solutions ensure superior impact resistance, corrosion protection, and dimensional stability even in extreme climates.

Forklift Bodies: Enhanced Safety and Durability

In industrial warehousing and logistics, forklift bodies must balance safety and durability. FRP composites reduce weight and cost while providing excellent impact resistance and surface finish, ideal for standardized mass production.

Machinery Housing Manufacturing: Combining Mass Production and Customization

As project demands diversify, machinery housing manufacturing must address both structural performance and aesthetics. Sanse leverages years of experience in composite mold development and molding to offer full-cycle customization from design, CAE simulation, mold fabrication to surface treatment and painting.
