Client Profile
| Industry |
Consumer Electronics & Home Appliances |
| Company Size |
Large Enterprise (2,000+ employees) |
| Geography |
Noida, Uttar Pradesh, India |
| Operational Context |
The client excels in manufacturing control panels, display housings, and decorative trims for consumer electronics and home appliance enclosures constructed of high-quality aluminum and stainless steel. Tactile feel is just as significant as visual appeal because the components are available to end users and directly affect the product's perceived quality. |
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.
