What is Plastic Media?
Plastic media is made from engineered polymer materials, often with additives to improve hardness, elasticity, and durability. It is designed to safely finish surfaces without damaging soft or delicate components.
- Safe on delicate parts: Less aggressive than ceramic or aluminum oxide.
- Efficient deburring: Removes burrs and sharp edges effectively.
- Reusable: Can withstand multiple cycles depending on the process.
- Customizable: Available in different shapes, sizes, and hardness grades.
Types and Specifications
Plastic media comes in various shapes and hardness grades. Each type is tailored to specific industrial applications.
| 类型 | Shape | 硬度 | 应用 |
|---|---|---|---|
| Plastic Tumbling Media | Triangular / Cylindrical | Medium | Deburring and polishing metal and plastic components |
| Plastic Shot | Round | Soft | Finishing delicate electronic and automotive parts |
| Specialty Plastic Media | Custom | Varies | Industry-specific surface treatment and polishing |

Industrial Applications
Plastic media is widely used in industries where surface safety and efficiency are both critical:
- Automotive: Polishing dashboards, engine covers, and delicate components without scratching.
- Electronics: Safe finishing of circuit boards and small electronic parts.
- Medical devices: Polishing surgical instruments without removing surface coatings.
- Precision manufacturing: Surface finishing of molds, plastic parts, and delicate assemblies.

Advantages vs Other Media
Plastic media is softer than ceramic or aluminum oxide, making it ideal for delicate surfaces while still providing effective finishing:
- Vs Ceramic Media: Less aggressive, safer for soft or coated surfaces.
- Vs Aluminum Oxide: Reduces risk of scratching and maintains surface integrity.
- Cost-effective: Longer life when used on delicate parts compared to harder media.
Selection Guide & FAQ
When selecting plastic media, consider the part material, desired finish, and the media shape/hardness:
- Soft parts: Use soft round plastic media to avoid surface damage.
- Deburring and light polishing: Medium hardness triangular or cylindrical media works well.
- Special applications: Consult your supplier for custom media formulations.
FAQ
- Q: Can plastic media be used on coated surfaces?
- A: Yes, plastic media is ideal for coated or painted surfaces because it reduces the risk of scratching or coating removal.
- Q: How long does plastic media last?
- A: Depending on usage, plastic media can last several cycles. Reuse is typically higher when used on softer materials.
- Q: Which shape of plastic media is best for deburring?
- A: Triangular or cylindrical media provides effective burr removal while maintaining safety for delicate parts.
