How to Produce Sheet Moulding Compound?

Sheet Molding Compound (SMC) is a ready-to-mold, glass-fiber-reinforced thermoset composite supplied in sheet form and processed mainly by heated compression molding.
It combines a thermosetting resin system with glass-fiber reinforcement and other formulation components to produce repeatable molded composite parts.
SMC is selected according to the finished application. Electrical insulation, outdoor components, Class-A vehicle parts and lightweight components require different balances of strength, density, shrinkage, flame behavior and surface quality.

Choose the Right SMC for Your Application

Different molded parts require different combinations of mechanical performance, electrical properties, surface quality, density and dimensional stability. Start with your application and identify the most suitable SMC reference grade.

SMC Compression Molding Guide

SMC is mainly processed by heated compression molding. The following values provide a starting process reference based on the supplied TDS information. Actual molding conditions should be adjusted according to the formulation, part geometry, mold and press.

Process: SMC Charge Preparation → Charge Placement → Mold Closing → Compression & Curing → Demolding → Finishing & Inspection

Parameter

Compression Time

Approximately 1 minute per 1 mm of finished-part thickness

Upper Mold Temperature

Why Choose JLON for Sheet Molding Compound?

 

Application-Based Grade Selection

 
line
 
We start from the molded component and target performance instead of pushing one generic SMC grade for every application.
     

 

Custom Requirement Review

 
line
 
If a standard reference formulation does not match your project requirements, send your current TDS or target specification for review.
  

 

Technical Data First

 
line
 
Compare glass-fiber content, shrinkage, water absorption, mechanical performance, density and application-specific properties before starting a molding trial.
  

 

Molding Support

 
line
 
Material selection can be reviewed together with mold temperature, compression time, press capacity, projected area and molding conditions.
  

 

Multiple Reference Formulations

 
line
 
Our current SMC portfolio covers electrical, high-strength, weather-resistant, vehicle, water tank, reinforcement, Class-A, sanitary and lightweight applications.

Frequently Asked Questions About Sheet Molding Compound

  • Q What is Sheet Molding Compound (SMC)?

    A Sheet Molding Compound is a ready-to-mold, glass-fiber-reinforced thermoset composite supplied in sheet form and processed mainly by heated compression molding.

  • Q Is Sheet Moulding Compound the same as Sheet Molding Compound?

    A Yes. “Sheet Molding Compound” is the American English spelling, while “Sheet Moulding Compound” is the British / European spelling. Both are commonly abbreviated as SMC.

  • Q How do I choose an SMC grade?

    A Start with the finished component, application, required performance and molding conditions. JLON can compare these requirements with the available application-specific SMC reference formulations.

  • Q Can SMC achieve UL94 V-0?

    A Selected reference grades are specified as UL94 V-0 in the supplied TDS information. The applicable test thickness should be confirmed from the underlying test report before publication or project approval.

  • Q Which SMC grade is suitable for electrical insulation?

    A JLONSMC5004 is the current electrical reference grade. Its supplied data includes electrical strength of ≥12 kV/mm, arc resistance of ≥180 seconds and tracking resistance index of ≥600 V.

  • Q Which SMC grade has the highest mechanical strength?

    A JLONSMC1001 has the highest listed tensile strength at 160 MPa and flexural strength at 320 MPa among the supplied reference grades. JLONSMC6006W has the highest listed impact strength at 100 kJ/m².

  • Q Is there a low-density SMC for lightweight applications?

    A Yes. JLONSMC9009 has a listed density of 1.45 g/cm³ and is positioned for lightweight applications.

  • Q Which SMC is suitable for Class-A vehicle surfaces?

    A JLONSMC6008A4 is positioned for vehicle structural and large parts requiring Class-A surface quality. Its listed shrinkage is 0.05%.

  • Q Can SMC be used for sectional water tanks?

    A Yes. JLONSMC6006SX is designed for sectional water tank panels, and the supplied TDS states that the grade has passed WRAS certification.

  • Q What are the typical SMC compression-molding conditions?

    A The supplied TDS information gives a starting reference of approximately 1 minute per 1 mm of finished-part thickness, an upper mold temperature of 146–150°C, a lower mold temperature of 138–142°C and a press-force reference of approximately 1000 tons/m² of projected area. Final conditions should be adjusted to the actual part and process.

  • Q How can I get a suitable SMC material recommendation?

    A Send your current SMC TDS, target specification, molded-part drawing or application requirements. JLON can review the requirements and recommend an appropriate starting grade or formulation direction.
