Application

It is widely used for manufacturing high-end custom-mold UV resin in-ear monitors, customized hearing aid shells, and casting of special-shaped parts.

Specification Parameters

Performance Description

1. High Hardness & Polishable Shore D hardness:78. The shell can be polished. It supports shell thickness down to 0.3mm, sturdy and scratch-resistant.
2. High Toughness High toughness shell with excellent impact resistance, easy for subsequent drilling and machining. Test: A cone indents 0.9mm thick shell inward over 1mm under 1.1kg thrust, shell remains intact.
3. Uniform Shell Formation Precise wall thickness control at different positions of the shell. Smooth inner & outer surface, high consistency and easy processing.

Note: Picture shows ear shell without polishing or top clear coat.

Caliper test data: Upper edge wall thickness: 0.51mm Lower edge wall thickness: 0.61mm

1. Custom Color Available The casting UV resin can be tinted as required.

Operating Steps

1. Slowly pour UV resin into the mold (do not overflow), then cover the top with a black light-shielding material.
2. Place under UV nail lamp for 25-35 seconds irradiation. (Adjust time according to target wall thickness.) At this stage, the cured resin thickness on mold inner wall reaches approx.0.9-1.7mm (judge based on actual curing condition).
3. Take out the mold and pour out uncured UV resin liquid. Do NOT pour it back into the original container.
4. Cover the mold with transparent glass or PET film, flip it over (base facing upward), irradiate under UV nail lamp for 30 seconds.
5. Remove the mold, take out cured earphone shell, immerse fully into prepared cleaning solution.
6. Place cleaning solution together with earphone shell under UV nail lamp and irradiate for 4-6 minutes.
7. Take out cleaning solution and earphone shell, retrieve shell and rinse with water or ethanol.
8. Post-processing of earphone shell: polishing, drilling, cutting and other processing until finished.
9. After use, tighten the cap tightly, store sealed at room temperature away from light.

UV Lamp Requirement for Curing

• General UV nail lamp with power >36W
• Or other UV lamps that meet curing requirements

Surface Hardening: Use with TADHE surface cleaning solution
