Rally Plastic has a state-of-the-art quality control laboratory capable of conducting rigorous testing on your optical injection-molded parts and molds.
Eliminate the risk of dim, distorted, or hazy light output. We utilize advanced spectrophotometers and light transmittance meters to inspect your custom lighting components. You receive guaranteed 92%+ optical clarity for your PMMA or PC lenses.
Avoid assembly line downtime caused by dimension variations. Our engineers utilize advanced Coordinate Measuring Machines (CMM) to verify your custom lighting components against CAD models. We enforce strict tolerances down to ±0.005mm, ensuring perfectly flush fitment and precise optical alignment for your plastic housing for led lights every time.
We place your plastic led light housing into accelerated UV aging and thermal cycling chambers. By simulating years of intense sunlight and extreme temperature swings, you are guaranteed an led plastic housing that maintains its pristine exterior aesthetic and mechanical strength for decades.
To accelerate your time-to-market, our tooling engineers conduct a comprehensive DFM (Design for Manufacturability) analysis before cutting steel to optimize your lighting components for flawless mass production. Once the mold is built, we deliver rapid T1 physical samples, allowing you to rigorously evaluate optical performance, assembly fitment, and dimensional accuracy for your custom plastic housing for led lights.
Protect your transparent lenses and housings from transit damage. We utilize individual anti-scratch films, custom anti-static PE foam trays, and dust-free sealed bags, ensuring your sensitive optical components arrive 100% pristine and ready for assembly.

To prevent sink marks in thick-walled PC or PMMA optical lenses, we utilize specialized injection profiling with extended holding pressures and precise cooling algorithms. By maintaining high mold temperatures and employing conformal cooling channels, Rally Plastic ensures uniform shrinkage across thick sections. Additionally, running moldflow simulations before tooling allows us to optimize gate size and placement, maintaining continuous material packing until the gate freezes, effectively eliminating internal bubbles, stress birefringence, and surface depressions.
Weld lines on transparent lighting covers cause severe optical distortion and mechanical weakness. To eliminate them, we optimize the runner system and gate locations using advanced Moldflow analysis, ensuring a continuous, unidirectional melt front. We also implement high mold temperature control—sometimes utilizing Rapid Heat Cycle Molding (RHCM)—to keep the resin flow front highly fluid until the cavity is completely filled. This prevents premature cooling and ensures the polymer chains fuse seamlessly, delivering a crystal-clear, distortion-free finish.
Gate design is paramount for optical clarity. For thick optical lenses, we typically employ edge gates or fan gates to provide a broad, uniform flow front, minimizing shear stress and preventing jetting. For highly aesthetic transparent covers, we may use hot runner systems with precision valve gates to completely eliminate gate vestiges and reduce pressure drops. Our engineers rely on extensive DFM and Moldflow simulations to determine the exact gate geometry, preventing flow marks and internal stresses.
For high-power LED drivers and internal structural components, excellent thermal management is critical to prevent electronic failure. We highly recommend thermally conductive plastics, such as specialized PBT or PA (Nylon) grades reinforced with glass fibers and mineral fillers. These engineered thermoplastics provide superior heat dissipation capabilities, high continuous use temperatures (CUT), and excellent dimensional stability. Additionally, we mold UL94 V-0 flame-retardant PC/ABS alloys to ensure strict compliance with international electrical safety and fire resistance standards.
Outdoor luminaires are exposed to severe solar radiation, which degrades standard plastics. To combat this, we process specialized UV-stabilized and weatherable thermoplastic grades, such as outdoor-grade PC, PMMA, or ASA. These advanced polymers are formulated with UV absorbers and hindered amine light stabilizers (HALS) that block ultraviolet photon degradation. Furthermore, we can apply an additional protective UV-resistant clear coating post-molding, ensuring your lighting components maintain their mechanical toughness, impact resistance, and pristine appearance for years.
We process premium engineering plastics including ABS, PC, PP, PA, etc. equipped with injection molding machines ranging from 100 to 800 tons.
