Engineered for high durability and strict tolerances. Serving San José, Coyol, and Cartago industrial hubs.
Costa Rica has transformed into a leading Latin American hub for advanced manufacturing, dominated by the Life Sciences (Medical Devices), Aerospace, and High-Technology Electronics sectors. Strategic locations like the Coyol Free Zone in Alajuela and Global Park in Heredia host the world's leading OEMs. In these demanding arenas, components require extreme mechanical integrity, bio-compatibility, and complex geometries that conventional manufacturing cannot offer.
This is where Investment Casting (Lost Wax Casting) coupled with high-precision CNC Machining becomes vital. The capability to cast intricate configurations in medical-grade stainless steel or titanium, followed by micron-level CNC finishing, reduces material waste by up to 70% compared to solid stock machining while maintaining pristine mechanical parameters.
A trusted global supplier of precision casting, complex CNC machining, and multi-component assembly.
Dongguan SX Technology Co.,Ltd has very rich experience in precision casting, CNC machining and assembly. Our products are used in machinery, automobiles, marine, ships, equipment, valves and pumps, electronic appliances, packaging, watches, construction, chemical industry and other industries. The most commonly used materials for investment casting are stainless steel and carbon steel. And the most commonly used materials for CNC machining include titanium alloy, stainless steel, carbon steel, aluminum alloy, copper alloy, cemented carbide, etc. We have advanced manufacturing equipment and technology and are able to respond quickly to your needs.
By using the Silica Sol process for casting, we ensure surface roughness as low as Ra 3.2, minimizing post-machining requirements. Our 5-axis CNC machining centers then process critical interfaces to meet tolerances within ±0.005mm, satisfying the strict documentation and validation criteria essential for industrial applications across Costa Rica.
Providing high-precision components designed for localized engineering assemblies.
For Costa Rica's surgical instrument developers in Coyol Free Zone, we supply titanium and 316L stainless steel castings. These materials undergo post-casting milling to form components like endoscopic clamps, surgical scissors, and modular orthopedic trials requiring high bio-compatibility and sterilization durability.
Supplying high-strength, lightweight aluminum casting alloys (A356) and titanium alloys for components in the Heredia aerospace group. Applications include customized hydraulic manifold housings, sensor housings, and complex brackets engineered to survive high-vibration conditions.
Costa Rica's agricultural processing, food technology, and wastewater treatment plants depend on robust pumps and valves. Our corrosion-resistant CF8M/CF3M stainless steel investment castings provide impeller, housing, and structural valve configurations that stand up to corrosive media.
Combining structural integrity and surface quality to deliver near-net-shape components.
For applications where raw metal billet machining is cost-prohibitive due to material loss, we follow a two-tier hybrid roadmap:
| Material Class | Common Grades | Typical Use |
|---|---|---|
| Stainless Steel | 316L, 304, 17-4 PH, Duplex | Biotech, surgical tools, marine pump bodies |
| Aluminum Alloys | 6061-T6, A356, 7075-T6 | Avionics enclosures, electronics structural housings |
| Titanium Alloys | Ti-6Al-4V (Grade 5), Grade 23 | Implant trials, aerospace components |
Amid global supply chain volatility, Dongguan SX Technology Co.,Ltd ensures reliable delivery schedules for Costa Rican medical device hubs and electronics assemblers. Our location in Dongguan, China, integrates raw material sourcing, casting foundries, heat treatment, surface finishing, and 5-axis CNC machining facilities within a tight radius, minimizing transit downtime during production.
We work directly with major logistics providers to offer customs clearance support, standard packaging, and optimized sea or air freight to Juan Santamaría International Airport or Puerto Caldera. With the China-Costa Rica Free Trade Agreement (FTA), importing cast and machined parts from our facility remains a cost-effective choice for OEM purchasing teams looking to balance quality and price.
Continuous investment in inspection machinery to achieve precision tolerances.
Quality control: We have professional testing equipment and professional QC personnel, and we adhere to strict tolerances and quality standards for the products we produce. Due to our insistence on strict quality requirements, we have been praised by many customers.
Quality is the cornerstone of the manufacturing industry. We firmly believe that only by controlling quality well can we survive, develop, and get better and better. Therefore, we have been working in this industry unremittingly since 2014 and continue to Improve the company's team and improve the company's production capacity.
Our quality assurance workflow features material chemistry analysis via Optical Emission Spectrometry (OES), non-destructive testing (NDT) via Liquid Penetrant and X-ray Inspection, and dimension validation using Coordinate Measuring Machines (CMM) to meet precision specifications before shipment.
For Costa Rica's export-oriented manufacturing firms, compliance with international standards is essential. We support medical device manufacturers and industrial partners by providing robust quality documentation:
This systematic documentation streamlines receiving inspection at your manufacturing site in San José or Heredia, avoiding quarantine delays and keeping production lines running efficiently.
