Welcome to Xi'an Prima Beauty Equipment Co., Ltd., your trusted global partner in high-performance aesthetic technology. With over 10 years of specialized manufacturing experience, our head office strategically integrates front-end semiconductor research, high-power diode laser micropackaging, and state-of-the-art solid-state laser systems with end-market medical beauty machine production.
We serve professional distributors, medical clinics, and laser technicians globally. By manufacturing premium diode laser stacks, CO2 fractional lasers, Pico Q-switched lasers, and IPL machines under strict ISO protocols, we deliver unmatched clinical efficacy and maximum return on investment for partners worldwide.
The landscape of laser epilation is shifting towards pain-free operation, multi-wavelength convergence, and extreme pulse longevity. Here is how our optoelectronic solutions lead the industry.
Traditional macrochannel coolers face thermal thresholds that limit laser duty cycles. Our MCC packaging technology utilizes stacked micro-capillary copper plates, allowing cooling water to pass directly through the interior of the laser bar array. This keeps the junction temperature of the diode bar below 55°C even during continuous 10Hz firing, dramatically reducing thermal fatigue and extending stack lifetime up to 50 million shots.
Indium migration under high operating temperatures is the leading cause of dead bars in inferior laser modules. Our factory implements high-vacuum AuSn gold-tin alloy reflow soldering. By completely replacing indium, we eliminate solder voids and prevent electro-thermal degradation, ensuring our high-power stacks (up to 4800W) withstand heavy-duty medical workloads without performance degradation.
To cater to diverse Fitzpatrick skin types, we have pioneered the integration of four distinct wavelengths (755nm, 808nm, 940nm, 1064nm) into a single, cohesive diode stack. This multi-wave structure targets the melanin (755nm/808nm), the capillary feeding network (940nm), and deep follicular papillae (1064nm) simultaneously, ensuring a highly effective and virtually painless treatment experience.
Integrating real-time thermal sensors into the handpiece sapphire tip. The laser control system automatically modulates pulse width and energy density dynamically in milliseconds based on the contact temperature, guaranteeing a complete absence of surface thermal shock.
Moving towards customized vertical-cavity surface-emitting lasers (VCSEL) combined with macro/micro lenses. This roadmap targets a 30% reduction in driving current requirements, keeping overall system heat production exceptionally low while achieving equivalent optical power output.
Our corporate philosophy centers around high technology, rigorous quality verification, and comprehensive OEM/ODM customization capabilities.
As a leading Chinese supplier of mid-to-high-end beauty equipment components, we do not merely assemble parts. We integrate laser chip packaging, wafer-level mounting, optical lens polishing, and control driver development under one roof. Our R&D division has spent a decade refining diode stacks, providing our clients with the latest advancements in vertical-array cooling and pulse frequency modulation.
Reliability is critical in professional aesthetics. Every laser diode module and fully integrated machine undergoes a 48-hour continuous aging test, pressure cycle tests for fluid channels, and spectral output calibration. We support custom parameters, selecting specific wavelengths and power ratings (e.g., 600W to 4800W) to align precisely with your clinical requirements.
We provide full-spectrum branding and mechanical engineering support. From designing custom handle shapes and modifying software GUI systems to tailoring internal laser stacks for compatibility with third-party housings (like Alma, Lumenis, etc.), we enable medical beauty hospitals, salons, and distributors to build strong, localized brand equity.
We support the entire lifecycle of professional hair removal systems, ensuring minimal downtime and optimized machine performance.
One of the most significant cost centers for medical beauty clinics is the replacement of worn-out handpieces. Most manufacturers require you to purchase an entirely new handle once the diode stack fails.
Xi'an Prima provides a sustainable, cost-effective alternative. We manufacture OEM/ODM-grade replacement laser stacks specifically designed for handle rebuilding. Technicians can replace the interior diode module, swap the microchannel plates, and reseal the light-guide crystal, saving clients up to 70% in maintenance fees.
Our facility in Xi'an implements precise cleanroom workflows and advanced automation, delivering high reliability with efficient production lead times.
Micro-packaging of semiconductor laser chips is highly sensitive to dust and airborne particles. Our cleanroom facilities maintain strict controls over air particulates, relative humidity, and static electricity, preventing early chip contamination and ensuring stable long-term light output.
We utilize automated machinery for component alignment and eutectic die bonding. Minimizing manual placement deviations ensures uniform current density across the laser diode bar, reducing hot spots and early failures.
By managing everything from basic bar mounting to the assembly of finished systems, we reduce intermediate procurement costs and simplify quality tracking, passing these cost savings directly to our global wholesale clients.
When sourcing painless diode laser arrays or complete systems, prioritize technical specifications that impact overall operational lifespans and safety profiles.
Ensure the supplier provides detailed cooling specifications. Microchannel cooler (MCC) designs require deionized water with constant filtration, whereas Macrochannel (macro-channel) designs are less sensitive to water quality but operate at lower maximum power levels. Verify that the inner structural coatings prevent galvanic corrosion.
Confirm the origin of the diode laser chips. Top-tier German or US manufactured bars provide excellent electro-optical conversion efficiency. Additionally, specify AuSn hard soldering over traditional Indium packaging to avoid indium degradation under high duty cycles.
When ordering replacement stacks for handle repairs, match the drive current (A) and forward voltage (V) requirements of the host machine. Mismatches can cause driver board failures or degrade the laser bars due to over-current spikes.
Verify that the components comply with international standards. Reliable suppliers should offer certifications like CE, RoHS, and ISO 13485 to ensure smooth customs clearance and compliance with localized safety guidelines.
Our engineering facility operates in strict accordance with international standards, ensuring safety, reliability, and regulatory compliance.
Common questions regarding laser modules, handle repair, custom configurations, and international shipping.
Most stack failures stem from overheating, indium solder migration, or mineral buildup inside the microchannels. We address these challenges by utilizing AuSn hard soldering to prevent solder migration and applying corrosion-resistant gold plating to our copper heat sinks, protecting the cooling channels from degradation.
Yes. We specialize in custom configurations, adjusting the number of bars, stack width, height, and target wavelengths. We also modify mounting brackets and electrical connectors to align with your proprietary handle designs.
Different wavelengths target different structures. 755nm offers high melanin absorption for light skin and fine hair; 808nm is the classic choice for deep follicular penetration; 940nm targets capillarial hemoglobin to disrupt the hair root's nutrient supply; and 1064nm safely treats darker Fitzpatrick skin types by reducing epidermal absorption.
MCC modules use very small cooling channels. To prevent clogging and mineral buildup, they require deionized or double-distilled water with a conductivity below 5 uS/cm. We also recommend replacing the water filter cartridge every 3 to 6 months.
Under recommended operating conditions—including proper water flow, temperature control, and correct current parameters—our gold-soldered microchannel stacks typically deliver between 30 million and 50 million pulses before output power drops by 20%.
Yes, we provide full support components, including high-transmittance sapphire contact windows, TEC cooling plates, laser diode driver boards, and touch-screen control systems, facilitating complete device integration.
