Product Introduction:
Daruwin's Plastic Raw Material Colorful Beads is a closed-cell foam particle made from a unique process. The major characteristics of this product are the ultra-light texture as well as the highly efficient cushioning and shock absorption capabilities. During transportation and handling, it can absorb impacts and vibrations very well, it is also resistant to moisture uptake and can be made anti-static to prevent components from attracting dust or being damaged by static electricity. EPS particles can be molded with molds very flexibly to be perfectly fitted for various irregular and uniquely shaped products, thus securing the fixation as well as saving the space.
Where can it be used?
Positioning chip packaging boxes, modules, and relays
Electronic component turnover and transport boxes
PCB peripheral components protective inner boxes
Industrial control components and precision electronic accessories cushioning packaging
Exported electronic components packaging boxes with shock proof features
Why use EPS particles for electronic component packaging?
Electronic components are typically small in size and densely packed, requiring the internal structure of the packaging box to be very precise, with multiple positioning slots and stable dimensions, and a clean, blemish-free appearance. Due to the large production volume, any small instability factor will be significantly amplified. Daruwin's EPS beads for precision parts packaging foam exhibit good flowability, fast molding, and stable shrinkage rate, which perfectly meet the requirements of precision, efficiency, and consistency in electronic packaging.
| Model | Particle size (mm) | Foaming ratio | Suitable electronic component packaging boxes |
| B-302 | 1.0–1.43 | 45–65 | Large electronic modules, thick-walled boxes |
| B-303 | 0.7–1.0 | 40–60 | Standard electronic component packaging boxes |
| B-401 | 0.6–0.9 | 40–55 | Precision electronic components, multi-compartment boxes |
| B-501 | 0.4–0.7 | 30–50 | High-density, small-sized component boxes |
Daruwin's Production Capabilities:
Daruwin possesses its own R&D team, which has continuously improved the foaming stability of fine particles, ensured the integrity of complex and delicate structures, and guaranteed dimensional consistency in large-scale production over the years. These seemingly technical breakthroughs ultimately point to one goal: improving your production efficiency and final yield, and reducing your production debugging and loss costs. We have repeatedly verified and overcome practical problems through massive orders on our own factory production lines. Therefore, what we offer is not just a raw material, but a manufacturing solution based on in-depth practice that can directly stabilize your production capacity and improve quality.
Daruwin's Factory:
Temperature, pressure, stirring speed, additive ratio, reaction time, and aging conditions are those factors that directly influence the final performance of EPS during the production. All these key parameters are under real-time monitoring and adjustment by the control room. Through large monitoring screens and automated systems, operators are constantly informed about the production line status, such as polymerization temperature curves, reactor pressure fluctuations, steam delivery status, and water cooling system load. When any parameter value deviates, the control room immediately raises an alarm allowing the staff members to efficiently locate the problem through manual intervention or equipment adjustment. This real-time monitoring capability guarantees the production process to be confined within the desired stability parameter range thus avoiding deterioration of product performance resulting from temperature or pressure fluctuations that are too high.
FAQ
Q1: Is it suitable for small-sized, multi-cavity packaging boxes?
A: Yes, B-401 or B-501 are the products we recommend.
