SX Machining
High-quality investment castings designed to support the local modernization programs, heavy equipment manufacturing, and maritime logistics corridors.
The Philippines is experiencing a rapid transition towards advanced industrial manufacturing. Strategic programs like the Public Utility Vehicle (PUV) Modernization Program and infrastructure developments in the Calabarzon, Cebu, and Clark Special Economic Zones require high-durability metallic components. Direct sourcing from specialized casting plants has become a necessity for local manufacturers to maintain cost competitiveness.
Traditional sand casting techniques struggle to meet the strict tolerances and complex interior geometries required by modern automotive suspension, marine structural hardware, and industrial fluid control valves. Our Silica Sol Investment Casting provides components with surface roughness ratings under Ra 3.2μm, bypassing secondary finish-grinding while ensuring component integrity.
Replacement of obsolete casting parts in public utility buses and light rail networks with precision carbon and stainless steel structures.
Specialized stainless steels (316 & Duplex grades) configured to survive the high salinity environments of Cebu and Batangas maritime lanes.
Global supply chain disruptions necessitate partnering with manufacturers utilizing structured automated lines. Dongguan SX Technology Co., Ltd bridges the gap between China's raw material sourcing scale and the logistics needs of the Philippine manufacturing corridor.
Our casting facilities incorporate automated climate-controlled wax pattern cooling, high-efficiency robotic shell building, and computerized induction melt controls. This mitigates traditional human-error factors, producing chemical uniformity across batches of SUS314, SUS316, and high-performance carbon steels.
Direct routes from Shenzhen or Guangzhou ports to Manila North/South Harbor and Cebu International Port, reducing shipping times to under 10 days.
We provide full verification documentation, including Form E certificates, allowing Philippine importers to utilize preferential tariff concessions.

When procurement teams in Manila or Cebu evaluate casting bids, understanding the technical process is essential to component lifetime performance. Many budget foundries utilize the Water Glass investment process. While cheaper, water glass castings present a rougher surface finish (typically Ra 6.3–12.5) and lower dimensional accuracy, often resulting in hidden overheads due to excessive finish-machining.
Dongguan SX Technology exclusively offers high-grade Silica Sol casting. This process utilizes zircon sand and premium binders. The physical shell exhibits high stability during the thermal shock of alloy pouring, minimizing micro-tearing and ensuring pressure-tight casting structures suitable for chemical pumps, LPG pipeline systems, and high-pressure steam valves.
Every melt batch undergoes spectrometer validation. We match international standards including ASTM, DIN, JIS, and BS, providing standard EN 10204 3.1 material certifications.
With an in-house CNC machining workshop, we execute milling, tapping, boring, and turning on custom cast structures to deliver ready-to-assemble parts.
We execute standard inspection protocols to ensure component performance under load and in harsh environments:

Our standard manufacturing workflow operates as follows:
1. Tooling & Sample Phase: 15 to 21 working days for mold design, CNC tooling fabrication, and delivery of initial sample components with full dimensional inspection reports.
2. Batch Production: 20 to 30 working days depending on quantity, shape complexity, and requirements for post-casting CNC machining.
3. Shipping & Customs: Sea freight from Shenzhen to Manila takes approximately 7-10 days, and air freight takes 3-5 days.
Yes. We casting components to match global specifications including ASTM (e.g., A351 CF8, CF8M, CF3, CF3M), JIS (e.g., SCS13, SCS14A), and European DIN equivalents. Every shipment includes spectrometer-based chemical analysis results confirming carbon levels, chromium, nickel, and molybdenum content.
Our minimum order criteria typically depend on part weight and overall tooling complexity:
For small, light-weight components (less than 0.5 kg), our typical starting quantity is 100 to 500 units. For heavier, complex items (above 5 kg), we accept production runs starting at 50 to 100 units. We also support prototype validation projects during the early-stage engineering phase.
To resist galvanic corrosion and saltwater damage, we recommend utilizing grade 316 / 316L (CF8M/CF3M) stainless steel or duplex alloys. Following the shakeout process, parts undergo acid pickling and chemical passivation. This chemical treatment removes free iron from the component surface, creating a protective chromium oxide layer that prevents oxidation.
Yes. Under the ASEAN-China Free Trade Area (ACFTA), we issue Certificate of Origin Form E documents for our Philippine customers. This document allows importers to qualify for zero-tariff or reduced-tariff import classifications, lowering total landing costs.
We work directly with standard 3D CAD formats, including STEP (.step, .stp), IGES (.iges, .igs), and SolidWorks (.sldprt), alongside 2D PDF technical drawings indicating specific linear dimensional tolerances, surface finish specifications, and quality validation criteria.
