Compression Tooling for High-Performance Composite Molding

At Zhejiang MDC Mould Co., Ltd., we specialize in the design and manufacturing of advanced compression tooling for a wide range of composite materials, including SMC, BMC, GMT, and carbon fiber. With decades of experience in composite mold development, MDC provides turnkey tooling solutions that meet the most stringent demands of the automotive, electrical, sanitaryware, and construction industries.

What Is Compression Tooling?

Compression tooling refers to precision-engineered molds used in the compression molding process to form thermoset composite materials under high temperature and pressure. These molds are typically made of hardened tool steel and comprise an upper and lower cavity. During production, the composite material—such as Sheet Molding Compound (SMC) or Bulk Molding Compound (BMC)—is placed into the mold cavity and pressed into shape.

The efficiency, accuracy, and durability of the tooling directly impact the final product’s quality, mechanical performance, and production cost. That’s why selecting the right compression tooling partner is critical.

Our Expertise in Compression Tooling

MDC Mould is a trusted name in the global composite molding industry, delivering high-precision compression tools for:

• Automotive parts (EV battery enclosures, trunk boards, splash shields)
• Electrical enclosures and battery covers
• SMC water tanks and bathroom components
• High-strength GMT structural panels
• Carbon fiber performance parts

With in-house capabilities covering tool design, 3D modeling, mold flow analysis, CNC machining, mold assembly, and mold tryout, we control every stage of the tooling lifecycle.

Compression Tooling Process at MDC

Our standard compression tooling process includes:

1. Product Analysis: We begin by analyzing customer part geometry, material flow, and expected tolerances.
2. Tool Design: Using advanced CAD/CAM software, our engineers design the mold to meet performance and durability goals.
3. Tool Steel Selection: We use high-grade P20, H13, 718H, or other steels based on required hardness, thermal conductivity, and wear resistance.
4. CNC Machining: Precision machining is performed in-house using 3-axis, 4-axis, and 5-axis CNC systems for maximum accuracy.
5. Polishing & Surface Treatment: Polished or textured surfaces are applied according to the product design—chrome plating, Teflon coating, or mirror finishes available.
6. Tryout & Sampling: We conduct complete mold tryouts with hydraulic press machines and provide test samples before delivery.

Advantages of MDC Compression Tooling

• High Precision: Tolerances controlled within ±0.05 mm ensure consistent product dimensions and fit.
• Durability: Hardened tooling with optimized cooling systems increases mold life and production efficiency.
• Versatility: Compatible with thermoset materials such as SMC, BMC, GMT, and carbon fiber preforms.
• Customization: Fully customized mold cavities, lifters, ejector systems, and surface textures to suit each client’s product requirements.
• Complete In-House Manufacturing: All stages—from design to polishing—are performed under one roof.

Applications of MDC Compression Molds

Our compression molds are used in a wide range of industries:

• Automotive: SMC trunk lids, EV battery trays, fenders, hoods
• Construction: GRP panels, water tanks, utility covers
• Electrical: Circuit breaker enclosures, junction boxes
• Sanitaryware: SMC bathroom walls, bathtubs, ceilings
• Rail & Aerospace: Lightweight GMT/carbon fiber interior panels
