Description:FIELD OF INVENTION:
[001] The invention disclosed herein is related to device for treating polymers and more particularly is pertained to device for curing polymers.
BACKGROUND:
[001] Various acrylic curing machines have been developed over the years to address some of the aforementioned challenges. These prior art systems typically employ conventional curing methods, such as UV lamps, infrared heating, or combinations thereof. Some systems incorporate conveyor belts or rotating fixtures to facilitate even curing, while others offer rudimentary control over curing parameters.
[002] However, these existing solutions often fall short in delivering consistent and efficient acrylic curing across a wide range of formulations and product sizes. There remains a need for an improved acrylic curing machine that can overcome these limitations and provide precise, energy-efficient, and versatile curing capabilities for acrylic-based products.
[003] Acrylic materials are widely appreciated for their versatility and aesthetic appeal, but they require precise curing processes to achieve desired mechanical and optical properties. The curing process involves the polymerization of acrylic monomers into a solid, transparent form. Conventional manufacturing methods involved manually assembling the signages with 040 acrylic,.
