In today’s industrial manufacturing landscape, supply chain agility and design freedom are the defining factors of market competitiveness. As a procurement manager or R&D engineer, are you currently struggling to find a Sand Casting Supplier that can resolve these common pain points?
Pain Point 1: Traditional tooling lead times stretch for weeks or months, severely delaying New Product Introduction (NPI).
Pain Point 2: Complex geometries (such as internal cooling channels or lattice structures) are impossible to mold using traditional methods, limiting design innovation.
Pain Point 3: It is difficult to find a partner who understands traditional foundry metallurgy while possessing advanced digital manufacturing capabilities.
Welcome to Beijing 3D Printing Technology Inc. (3DPTEK). We are not just an advanced 3D printing equipment manufacturer; we are your trusted global casting service partner.
Our Unique Advantage: Powered by In-House Technology
Unlike standard foundries, 3DPTEK holds a unique "dual identity." Since 1994, we have been a pioneer in China’s 3D printing industry (formerly known as Longyuan AFS).
Why does our "In-House Equipment" matter to you as a casting buyer?
Most casting service providers rely on purchased equipment, leaving them vulnerable to high maintenance costs and technical "black boxes." At 3DPTEK, the 3DPTEK-J Series sand 3D printers used to produce your orders are entirely developed and manufactured by us.
Battle-Tested Reliability: Our machines don't just sit in a showroom. They operate in our own 3D Casting Centers across Anhui, Hebei, and Shandong, enduring tens of thousands of hours of rigorous, industrial-level operation. This means your orders are never delayed by equipment downtime.
Cost & Capacity Benefits: By controlling the core equipment and binder technology, we offer highly competitive pricing. We operate a fleet of over 25+ industrial sand printers (including the massive 3DPTEK-J4000 with a build volume of 4000×2000×1000mm) and 20+ SLS systems, creating a robust rapid manufacturing matrix.
Technical Closed-Loop: Our "Trinity Innovation System" (Research Institute + Postdoc Station + R&D Team) ensures we can solve the toughest casting challenges, optimizing everything from material formulas to printing strategies for your specific parts.

Core Capabilities: One-Stop Delivery from Blueprint to Casting
3DPTEK provides comprehensive casting solutions based on Binder Jetting and SLS technology. Here is how we redefine "Rapid Casting":
1. Rapid Delivery Speed
Based on our production data, switching to 3DPTEK technology delivers immediate results:
Cycle Time Reduced by 80%: We eliminate the time-consuming pattern design and tooling manufacturing processes.
Record Delivery: From CAD data receipt to finished casting delivery in as little as 5-7 days.
Real-World Speed: For a new energy commercial truck control box (wall thickness 4-7mm), we delivered 2 fully finished samples in just 5 days.
2. Unmatched Geometric Complexity
Thanks to Patternless Manufacturing, we are liberated from the constraints of draft angles and parting lines.
Integrated Molding: We can print complex assemblies—such as engine blocks or motor housings with spiral cooling jackets—as a single, integral sand mold.
Applications: Engine blocks, cylinder heads, complex impellers, hydraulic valve bodies, and EV motor housings.
3. Extensive Material Versatility
Our foundry centers are equipped with advanced melting and pouring facilities supporting a wide range of alloys:
Aluminum Alloys:ZL101A, ZL104A, A356, etc., ideal for lightweight automotive and aerospace components.
Cast Iron: Gray Iron (HT250/HT300) and Ductile Iron (QT400-QT600), perfect for heavy machinery bases and gearboxes.
Steel & Stainless Steel: Offering superior mechanical properties for high-pressure valves and energy equipment.
Copper Alloys: Specialized for marine pumps, valves, and wear-resistant parts.
4. Comprehensive Post-Processing & QA
We understand that casting is just the first step. 3DPTEK offers complete turnkey services:
Heat Treatment: T6 treatment and aging furnaces to ensure material properties meet specifications.
Precision Machining: Equipped with 5-axis gantry machining centers, vertical machining centers, and CNC lathes (Siemens systems) for micron-level precision.
Quality Assurance (QA): Our global-standard labs feature CMMs, X-Ray NDT (for internal porosity checks), Spectrometers (for chemical composition), and 3D Scanners.
Certifications: Fully certified to ISO 9001, ISO 13485 (Medical), and ISO 45001 standards.
Success Stories: Empowering Industries with 3DPTEK Technology
Our technology successfully serves industry leaders in automotive, aerospace, machinery, and energy sectors globally.
Case A: Automotive - New Energy Heavy Truck Subframe
The Challenge: Massive size (1000×570×500mm), thin walls (5.5mm), and complex geometry. Traditional tooling was too expensive and slow.
The Solution:3DPTEK sand printing combined with CNC precision engraving.
The Result: Achieved integral molding of complex curved surfaces without assembly. We delivered the prototype in 15 days, helping the client secure a first-mover advantage.
Case B: Industrial Machinery - Complex Impeller
The Challenge: Right-angle connections between blades and hubs with intricate internal flow channels. Traditional casting yields were critically low.
The Solution: High-precision 3D printed sand molds (400 DPI resolution) combined with gravity casting.
The Result: Surface quality surpassed traditional methods. Dimensional accuracy reached CT7 level, with fluid dynamics perfectly restoring the original design intent.
Case C: High Voltage Energy - 1100KV GIS Housing
The Challenge: Zero defects required. Must pass strict airtightness tests and flaw detection.
The Solution: 3D printed sand mold + Low-Pressure Casting (LPC).
The Result: Passed airtightness tests on the first try with a dense internal structure, saving months of mold development time.
Global Vision: Your Localized Partner
3DPTEK is actively expanding its global network. In addition to our massive manufacturing hubs in China, our equipment and services are trusted by partners worldwide, including Fonderia Italy, SLB/Redulit (Russia), KNC (Korea), and Akdas & Samsun Makina (Turkey).
We possess a professional export logistics team familiar with international trade standards (Incoterms), providing customized packaging and logistics solutions to ensure your castings arrive safely and on time, anywhere in the world.
