What is Silk Screen Printing in Injection Molding?

Silk screen printing, also known as screen printing, is a versatile post-molding decoration technique that involves pushing ink through a mesh screen to imprint detailed images, text, or logos on plastic parts. Each color in a design requires a separate screen, and the ink is applied only where the design permits—resulting in crisp, clean graphics with long-lasting durability.

Why Choose Silk Screen Printing?

• Cost-effective for multi-color designs: Ideal for plastic parts requiring vivid, multi-color branding or instructional elements.
• Versatile application: Works well on flat, curved, or irregular surfaces with proper screen adaptation.
• Strong adhesion: When surfaces are properly prepared, screen printing inks adhere tightly, resisting wear and chemical exposure.

Preparation is Key: Surface Energy & Cleaning

To ensure successful ink adhesion, Goldwin takes surface preparation seriously. Plastic parts are cleaned using methods like CO₂ snow-jet, ionization, or plasma activation to eliminate contaminants and increase surface energy. These steps are crucial because injection-molded plastics often develop static charges that attract dust and debris.

Optimizing the Process for Quality Results

• Custom tooling: Our mold designs consider downstream screen printing requirements—minimizing cutouts, deburring, and surface unevenness.
• Surface texturing: We can apply mild etching to improve ink grip and ensure uniform coverage.
• Durable finishes: Through careful ink selection and environmental testing, we deliver printed graphics that withstand friction, humidity, and chemicals.

Color Matching Options

To achieve visual precision and branding consistency, Goldwin supports Pantone, RAL, and physical sample-based color matching. Whether you need a high-gloss finish or matte texture, our team ensures seamless reproduction of your desired aesthetic.

Applications of Silk Screen Printing

Silk screen printing is widely used across industries including electronics, consumer goods, medical devices, and automotive components. Examples include:

• ABS plastic parts for electronic housings
• Polycarbonate and nylon components with safety instructions
• Polypropylene promotional items with vibrant logos

Quality Control & Reliability Testing

Goldwin conducts stringent tests such as adhesion tape tests, chemical resistance, friction endurance, and environmental aging (heat, cold, humidity). We adhere to rigorous standards to ensure that the printed finish remains intact through the product’s life cycle.
