Sheet Molding Compound (SMC) Advanced Composite Materials

SMC is a high-strength fiber-reinforced board molding composite material, which is mainly composed of thermosetting resin, glass fiber and filler material. It is added with other different functional fillers and additives, such as shrinkage additives, pigments, mold release agents, catalysts, etc. It becomes a stable, moldable material for the production of various complex components. When we develop and manufacture our own basic products, we can supply a series of glass fiber raw materials in large quantities to meet the needs of any interested customers.

HAMC occupies a unique position in the field of reinforced plastics. The company combines 26 years of technical expertise in the die and composites industry with advanced design and manufacturing facilities.

SMC materials produce a large number of innovative custom molded products for a series of companies in today's broad industry sectors. It is ideal for the production of innovative products, and its versatility means that it can be effectively integrated into all industrial and commercial sector environments.

Features of Sheet Molding Compound (SMC)

Light weight, high mechanical strength, electrical insulation, fire resistance, corrosion resistance, heat resistance, weather resistance, low shrinkage, stable dimensional control, uniform material thickness, and a variety of special properties are integrated, making SMC the most ideal heavy-duty manufacturing material Truck/automobile body parts (Class A surface), indoor/outdoor cabinets for different equipment, molded door skins, various complex structural components in electrical or other industries.

Application of Sheet Molding Compound

Products made of this material have high impact resistance, compression resistance and bending strength.

SMC is used by the entire electrical market due to its many different functions, such as: resistance to provide insulation, conductivity and antistatic properties. These attributes are very suitable for highly specialized electrical products.

This material is also used in the automotive and transportation industries to produce large, high-strength items such as car seats.

The SMC formula means that it is colorable, so the finished product can be delivered to any color scheme chosen by our consumers. It also has low profile and low shrinkage characteristics, and has an excellent surface appearance, which is the perfect appearance for post-production spray paint.

From a safety point of view, the compound has low smoke, low toxicity and excellent chemical resistance. In essence, this material is ideal for a wide range of applications in many business areas.

Sheet molding compound (SMC) is widely used in the production of agriculture, automobiles, construction, electricity, energy, HVAC, lighting, military, rapid transportation, security, solar/wind energy, telecommunications, etc.

If you want to achieve the above-mentioned performance or reduce costs, you can usually use BMC/SMC to replace metal, concrete or thermoplastic materials.

Sheet Molding Compound (SMC) Development Process

Developing new products can be an expensive and challenging task. A good idea is not enough. The entire manufacturing process must be carefully designed to ensure maximum profitability. Any part may cause unnecessary delays or cost overruns. This is where HAMC can help.

When your project or component is very suitable for using SMC materials, contact us immediately to get the knowledge and help of the most professional team. We work closely with you to identify potential problems, analyze specifications and usage requirements, and begin to develop specific formulas to exceed the requirements of finished parts.

All necessary characteristics, such as flame retardancy or coloring, have been carefully reviewed and discussed. At this critical stage, our experts will maintain close and frequent communication with your engineers to ensure that all aspects of the project are thoroughly explored. After completing this process, we will proceed to the prototyping tool.

HAMC has a professional R&D team of engineers, cooperating with global partners such as AOC Aliancys Resins, BYK, Owens Corning and so on. We focus on the innovation, research and development of composite materials, the diversification of production methods, and the development of new applications with advanced properties of composite materials. Our team is responsible for realizing your needs and providing the greatest help to your business.

FAQs

1. What is HAMC’s product development process?

HAMC follows a structured, milestone-driven development process to turn concepts into production-ready SMC parts:

• Requirements & drawings: Customer submits specs, drawings and functional requirements (mechanical loads, surface finish, color, flame rating, environment).
• Technical negotiation & design development: Engineers perform feasibility, DFMA checks and material selection. HAMC proposes SMC formulations, reinforcement type, target thickness and preliminary cost estimates. Partners (resin and additive suppliers) are consulted for specialty requirements.
• Tooling making & trial runs (T1 & T2): Mold manufacture is managed to agreed tolerances. T1 is the first-article run to evaluate fit, flow and surface; T2 refines tooling and process parameters after T1 feedback.
• Testing & sample confirmation: Samples undergo dimensional, mechanical and surface tests (tensile/flexural/impact where required), paintability and any specified electrical or flammability checks. HAMC issues a test report and revises materials/processes if needed.
• Production: After customer approval, full-scale production begins with documented process control, traceability and final QC sampling before shipment.

Typical total development time varies by part complexity; HAMC provides a project schedule at kickoff and maintains close engineering communication throughout.

2. What production capacity and equipment does HAMC have?

HAMC maintains industrial-scale SMC/BMC production and forming capacity to support prototypes through mass production:

• SMC & BMC lines: 2 automatic SMC lines and 5 BMC lines for continuous compound production and batching.
• Compression presses: Multiple hydraulic presses from 100 to 4,500 tonnes, enabling small to very large-part molding and high-pressure consolidation.
• Annual capacity: Raw-material production capacity exceeds 20,000 tonnes per year, supporting steady supply and volume orders.
• Support equipment: In-house mixing, calendaring and cutting stations, plus prototyping presses and finishing/inspection cells for trimming, drilling and surface treatment.

These capabilities allow HAMC to scale from sample runs to high-volume batches while controlling lead times and quality.
