Custom Small Acrylic Display Case Factories & Service

Cast acrylic is produced by pouring liquid methyl methacrylate monomer between glass mold plates and polymerizing it in a hot-water bath or autoclave. This results in a superior molecular weight matrix, exceptional optical clarity (~93%), higher scratch resistance, and an attractive frosty-white laser engraving finish. Extruded acrylic is manufactured by continuously pushing acrylic pellets through an extrusion die; it provides tighter thickness tolerances and lower production costs, making it ideal for high-volume, thin, thermoformed point-of-purchase assemblies. For high-end display cases, cast acrylic is universally recommended for clean, solvent-welded edges and bubble-free bonds.

Crazing (micro-cracking) occurs when residual mechanical stresses from laser cutting or machining come into contact with solvent cement (such as methylene chloride). Xinquan mitigates this issue through two proprietary protocols: First, high-precision cases undergo diamond edge milling rather than direct thermal laser cutting for bonded interfaces, preventing thermal stress build-up. Second, components undergo a controlled thermal annealing cycle in an industrial oven (heating at approximately 75°C to 80°C for several hours, followed by slow cooling) prior to bonding. Our capillary solvent application occurs in cleanroom environments with strictly managed humidity to stop microscopic water vapors from causing internal joint haze.

Yes. Standard commercial PMMA inherently filters UV radiation below 300nm, but museum-grade specifications require comprehensive filtering up to 400nm. We stock and fabricate specialty museum-grade UV-filtering cast acrylic sheets (OP-2 and OP-3 equivalents). These sheets absorb up to 98%-99% of ambient UV-A and UV-B radiation, safeguarding valuable artifacts, signed athletic memorabilia, trading cards, and vintage ephemera from photochemical bleaching and material embrittlement over decades of indoor lighting exposure.

Prototyping turnaround generally takes 5 to 7 working days following CAD/artwork sign-off. Bulk mass manufacturing requires 15 to 25 business days, depending on batch quantities, laser engraving scale, and secondary retail packaging requests. As an agile custom factory, our baseline MOQ begins at 100 to 200 units for standard custom-dimensioned desktop cases, scaling to 10,000+ units for multi-store retail campaigns. Small custom pilot batches can be accommodated for initial product launch evaluations.

Because pristine optical surfaces are essential, each display case maintains its protective film (kraft paper or polyethylene film) through fabrication and assembly. Cases are sealed in non-abrasive polybags and isolated inside custom-molded high-density EPE foam cavities that suspend corners away from carton perimeters. Master shipping outers are constructed using 5-ply K=K corrugated export boxes. Full container orders and LCL shipments are palletized onto fumigated wooden skids, bound with heavy strapping, fitted with rigid corner guards, and wrapped in industrial stretch film to prevent maritime moisture ingress. Drop-test verification (ISTA-1A) is routinely completed for client audit protocols.

Our comprehensive post-processing fabrication includes high-resolution UV flatbed printing (CMYK + White + Varnish), precision CO₂ laser etching, rotary screen printing, and hot stamping. Structurally, we integrate polished metal cam locks, concealed rare-earth magnetic closures, clear acrylic hinges, bevel-cut bases in clear, mirrored, or frosted acrylic, integrated lighting ports, and multi-tier internal step risers built to your exact technical specifications.
