Precision Casting Facility: Delivering Complex Metal Components with Accuracy, Strength, and Scale
Juin 17, 2025
Baoding Longway Specializes in Lost Wax and Sand Casting Solutions for High-Demand Industrial Applications
In today’s advanced manufacturing landscape, the demand for intricately shaped, high-strength metal parts continues to rise across industries—from automotive and aerospace to energy and heavy equipment. Meeting that demand requires more than just molten metal—it requires engineering precision, repeatable quality, and scalable production.
Baoding Longway, a leading installation de moulage de précision based in China, delivers exactly that. With state-of-the-art equipment and decades of foundry expertise, the company produces both lost wax casting parts and large-format components through sand casting manufacturing, serving global OEMs and engineering firms with end-to-end casting solutions.
What Makes a Precision Casting Facility Different?
A precision casting facility, with metallurgical expertise, modern mold-making, and quality assurance installations is used to make components with vast array of features different from one another such as of:
- Tight dimensional tolerances (Correct)
- Complex internal geometries (Correct)
- Smooth surface finishes (Correct)
- Material traceability and mechanical strength (Correct)
Here at Baoding Longway, this goal is obtained by using investment casting (lost wax) and precision sand casting technologies as well as CNC machining and strict quality control standards.
Lost Wax Casting: Accuracy for Intricate Parts
Lost wax casting parts (also known as investment castings) are ideal for high-precision applications where surface finish and dimensional accuracy are critical. This method involves:
- Creating a wax pattern of the final part
- Coating the wax with ceramic slurry to form a mold
- Melting out the wax and pouring molten metal into the cavity
- Breaking the mold to reveal the finished casting
Baoding Longway’s lost wax casting capabilities support:
- Stainless steel, carbon steel, alloy steel, and non-ferrous metals
- Parts ranging from 50g to 50kg
- ±0.05mm dimensional accuracy
- Complex structures including undercuts, thin walls, and fine lettering
Typical applications include turbine blades, pump bodies, medical instruments, and customized hardware.
Sand Casting Manufacturing: Strength and Scale
For larger components or parts requiring thicker walls and robust durability, fabrication de moulage en sable remains the most efficient and economical option. Baoding Longway uses high-grade green sand and resin sand technologies for medium- to large-size industrial components.
Features include:
- Mold sizes up to 2 meters
- Casting weights up to 2 tons
- Grey iron, ductile iron, steel, and aluminum alloys
- Customized riser and gating system design for metallurgical stability
This process is widely used for automotive housings, machine bases, valves, and construction equipment parts.
Comprehensive Capabilities Beyond Casting
Baoding Longway is a corporation consisting of not only a foundry but also a complete manufacturing partner. In addition to its precision casting facility, the company operates:
- CNC machining for post-casting precision
- Heat treatment for mechanical property control
- Surface finishing including shot blasting, painting, and galvanizing
- Non-destructive testing (NDT) such as X-ray, ultrasonic, and dye penetrant inspection
All the parts are manufactured in an ISO 9001:2015 quality management system, and they come with material certification and the availability of dimensional inspection reports upon request.
