Dispensing & Sandblasting – The Finishing Touch for Detail Optimization, Key to Enhancing Product Texture and Performance
2025-02-18
Following the completion of silicone rubber compounding and mold making to produce basic finished parts, the dispensing and sandblasting process serves as the critical step that elevates products from "acceptable" to "premium". The two processes complement each other: dispensing focuses on sealing, bonding and gap-filling, resolving issues such as gaps and looseness in finished parts to boost structural stability; sandblasting is a surface treatment that removes burrs and oxide layers, resulting in a smoother, more uniform surface while enhancing surface adhesion to suit subsequent processing or end-use requirements.
Dispensing relies on professional equipment to accurately deposit and apply adhesives of compatible formulations to designated areas of the product. Once cured, the adhesive achieves reliable sealing or bonding. Its core requirements are precision, uniformity and no adhesive overflow, so that product performance is not compromised by improper glue volume or inaccurate application. Sandblasting propels abrasive particles onto the product surface via high-pressure air flow, eliminating defects through the impact of abrasives. The surface roughness can be adjusted as needed to meet the aesthetic and functional specifications of various industries.
These two processes are highly dependent on upstream procedures: high-quality compounded rubber ensures adequate flowability during dispensing, free from stringing or excess adhesive; high-precision molds reduce surface defects on semi-finished parts, lowering the workload of sandblasting. Whether for the sealing and protection of electronic components or the surface refinement of metal hardware, dispensing and sandblasting can significantly enhance product competitiveness, establishing itself as a key process that wins through superior details.
