Lighting Components: Thread Precision & Aesthetics

The Alliance of Fine Engineering and Design

In the high-end lighting sector, plastic must not only be functional, it must be beautiful. We produce trim and fastening components that meet the dual requirements of both designers and installers.

Our specialty? Revolution parts (rings, flanges, diffusers) integrating high-precision threading and uncompromising surface finishes.

1. Mastery of "Fine Pitch Threads" and Unscrewing

Successfully molding a plastic thread on a thin ring is a technical challenge. A single flash or oval deformation and the part is unusable.

We master advanced molding techniques for these geometries:

• Automatic unscrewing molds: For high-volume production, our tooling integrates rotating mechanisms (hydraulic motors or racks) that unscrew the cores before ejection. This guarantees a perfectly formed thread, without any parting lines that would break the pitch.
• Assembly precision: We guarantee smooth screwing (constant tightening torque) to facilitate the final assembly of the lighting fixture, even on very fine metric pitches (e.g., M20x1, M40...).

2. Exemplary "Aesthetic" Finish

On a lighting fixture, the retaining ring is often a visible part. It must present a look as high-quality as the glass or metal it accompanies.

• Zero visual defects: We optimize injection points (often sub-gates or pinpoint gates) so they are invisible once the part is assembled.
• Surface finishes: Our molds are mirror-polished to achieve high-gloss parts (Piano Black, Pure White) or textured via chemical graining for matte finishes that are silky to the touch.
• Absence of sink marks: Thermal management of the mold to avoid surface hollows, even directly above internal ribs or threading.
