High-End Consumer Electronics & Appliance Manufacturer

Client Profile

Business Challenge

The client was unable to get a uniform, luxurious-looking finish on the visible metal parts:

• Non-Uniform Surface Texture: The finishing techniques that the client used before made directional scratches and uneven textures, which were not acceptable for luxury products.
• Fingerprints & Lighting Issues: Fingerprints and glare appeared on the surface, which were extremely polished when seen under showroom lighting.
• Manual Finishing Bottlenecks: Considerable manual brushing and polishing were done to get the desired look of the product.
• Extremely High Rejection Rate: Surface flaws caused nearly 10% of the items to fail the cosmetic test.
• Brand Image at Risk: Minor cosmetic flaws could negatively impact consumers' perceptions of the products, potentially leading to worse ratings.

Solution Implemented

We chose Glass Beads blasting as the best method to get a well-controlled, luxurious surface texture after considering the desired tactile feel and visual appearance.

Specific Solution:

• Use of fine oval-shaped Glass Beads (70–120 microns) for micro-peening and cosmetic finishing.

Specific Solution:

• Use of low-pressure blasting to create a smooth, satin finish without any pattern.
• Controlled exposure to ensure the same effect on the flat and curved surfaces.
• Sealing the surface after the blast to improve the stain resistance.

Application Objective:

• Get a luxurious, refined matte-satin finish
• Reduce the effect of glare and fingerprints
• Get rid of directional machining marks without cutting into the material

Implementation Process

Timeline: Four weeks from the start of the trials to the approval of mass production.

Deployment Steps:

• Week 1: Experiments with different enclosure designs and materials.
• Week 2: Assessment of visual, tactile, and fingerprint resistance under showroom lighting.
• Week 3: Determination of bead size, parameters for blasting, and standards of acceptance.
• Week 4: Launch of production and training for the cosmetic inspection.

Training: Staff and quality inspectors were trained on visual acceptance standards and proper handling to maintain surface integrity after blasting.

Results & Impact

The Glass Beads process brought about significant changes in appearance and efficiency:

• Finish Uniformity: A consistent satin-matte finish was attained across all product variations.
• Decrease in Rejection Rate: Cosmetic rejections decreased from 10% to less than 1.5%.
• Manual Work Reduction: The utilization of manual finishing techniques was reduced by more than 60%.
• Boosted Customer Appeal: Better tactile and visual quality led to enhanced product acceptance.
• Brand Differentiation: The high-end finishing became the main selling point in advertising campaigns.

ROI & Business Benefits

• Decrease in Labor Costs: Cutting down on manual polishing and rework.
• Process Reliability: A scalable, large-volume, repeatable finishing solution.
• Faster Time-to-Market: Product launch timetables were enhanced, and finishing delays were decreased.
• Payback Period: Nearly 9 months, with labor cost savings and fewer rejections being the main factors.

Why the Client Chose This Company

The client gave us the priority over other companies due to:

• Aesthetic-Centered Engineering: We understood the market needs for surface finish and consumer features.
• Proof Through Trials: Only the physical samples and usage lighting conditions were taken into consideration for finish approval.
• Fine Media Expertise: Superior quality glass beads with high sphericity ensured that the results could be repeated.
• Continuous Support: Support was provided during the ramp-up and the launch of new product designs.
