Finishing SMC products
Finishing SMC (Sheet Molding Compound) products is an essential step in the manufacturing process of SMC composite parts. It is designed to ensure that parts meet the required design specifications and quality standards. Finishing comprises several important operations to prepare SMC parts for their final use. Here’s an overview of the main steps involved in finishing SMC products.
Step 04 Finish
Cutting
Cutting involves cutting SMC composite parts to the required size and shape. This can be done using specific cutting equipment, such as presses or laser cutting machines. Precise cutting is essential to ensure that parts fit correctly in the final assembly.
Drilling and machining
If required, holes or openings can be drilled or machined in SMC parts to allow the passage of cables, screws or other components. This can be done using conventional or CNC machine tools.
Deburring and polishing
The edges of SMC parts may show burrs or imperfections after cutting. Deburring consists in removing these burrs to obtain smooth, secure edges. In addition, polishing can be carried out to improve part aesthetics and ensure a uniform surface finish.

Coatings and paint
In some applications, SMC parts can be coated or painted to improve their appearance, weather resistance or chemical resistance. Coatings can be applied by spray or immersion processes.
Assembly
SMC parts can be assembled with other components to form a final product. This may involve attaching joints, reinforcing elements or fasteners.
Inspection and quality control
Before delivery of finished products, a thorough inspection is carried out to ensure that SMC parts meet design and quality specifications. This may include dimensional checks, strength tests and other product-specific tests.
The finishing of SMC products is crucial to ensure compliance with quality standards and to meet the needs of end-use applications. Finishing procedures vary according to product and industry specifications, but all aim to maximize the durability, appearance and performance of SMC parts.
