Quality and certifications: Check if the company has appropriate certifications, such as ISO 9001 or other industry-specific quality standards. These certifications indicate that the company follows established processes and maintains high-quality standards. Our foundry is a ISO9001-2015 certificated factory.

Request samples and references: Ask the casting companies for samples of their previous work to evaluate the quality of their castings. Additionally, request references from their existing clients and contact them to inquire about their experience working with the company.

Capacity and production capabilities: Determine whether the casting company has the capacity to handle your project. Consider factors such as production volume, lead time, and their ability to scale up production if needed. Our annual production capacity is more than 4,000 tons.

Technical support and collaboration: Assess the level of technical support and collaboration the casting company can provide. A reliable company should be able to offer guidance and expertise throughout the design and manufacturing process, suggesting improvements and optimizations where necessary. Our engineers can offer design and engineering support. We have experienced engineers who can review your designs, provide feedback, and offer suggestions for improving manufacturability and cost-effectiveness.

Pricing and affordability: Obtain quotes from multiple casting companies to compare pricing. However, remember that choosing the lowest-cost option may not always yield the best results. Consider the overall value, including quality, expertise, and reliability, along with the pricing.

Communication and responsiveness: Evaluate the communication skills and responsiveness of the casting company. Timely and clear communication is essential for a successful collaboration. Our sales team has good English skill and professional knowledge of investment casting.

Supply chain management: Consider how the casting company manages its supply chain. They should have established relationships with reputable material suppliers to ensure the quality and availability of materials. Efficient supply chain management can also contribute to shorter lead times and reduced costs. Our factory is close to Shanghai port and Ningbo port, we have our own exporting company in Shanghai and we have very reliable partners in inland transportation and international logistics field, in order to ensure our parts can be shipped or air world wide safe and in time.

Visit the facilities (if possible): If feasible, arrange a visit to the casting company’s facilities to see their operations firsthand. This will give you a better understanding of their capabilities, quality control processes, and the overall working environment. We welcome all the clients to pay a visit to our foundry in China.

By following these steps, you can make an informed decision when selecting an investment casting company that aligns with your project requirements and can deliver high-quality castings within your desired timeframe.

Please feel free to contact us and we look forward to building a long-term business relationship with you.

Investment casting, also known as precision casting or lost wax casting, offers several advantages over other casting methods. Here are some of the key advantages of investment casting:

Design flexibility: Investment casting allows for the production of complex and intricate shapes with high dimensional accuracy. It offers design flexibility, enabling the creation of parts with thin walls, fine details, and internal features that would be difficult or impossible to achieve with other casting methods.

Excellent surface finish: Investment casting results in parts with a smooth surface finish, reducing the need for additional machining or finishing operations. This can save time and costs in the production process.

Wide material selection: Investment casting supports a broad range of materials, including various alloys, stainless steel, carbon steel, tool steel, and superalloys. This versatility allows manufacturers to choose the most suitable material for the specific application requirements.

Cost-effective for small to medium production runs: Investment casting is particularly advantageous for small to medium production runs. It offers cost efficiencies in terms of material usage, as it minimizes waste compared to other casting methods. Additionally, the ability to consolidate multiple components into a single investment casting reduces assembly and labor costs.

High dimensional accuracy and repeatability: Investment casting yields parts with tight tolerances and high dimensional accuracy. The use of precision molds and wax patterns ensures consistent replication of intricate details, resulting in parts that meet precise specifications.

Wide size and weight range: Investment casting can produce parts ranging from a few grams to several kilograms in weight. This versatility makes it suitable for a wide range of applications across various industries.

Reduced need for secondary operations: Investment casting can often produce near-net-shape parts, reducing the need for extensive post-casting machining or other secondary operations. This can save time, costs, and material waste.

Improved part integrity: The investment casting process minimizes porosity and internal defects, resulting in parts with enhanced mechanical properties, structural integrity, and overall reliability.

Overall, investment casting offers the advantage of producing complex, high-quality parts with excellent surface finish and dimensional accuracy, making it a preferred choice for various industries, including aerospace, automotive, medical, and more.

Investment casting is a precision casting process that produces high-quality metal parts with complex shapes and fine details. Investment casting equipment are used to produce these parts, we suggest you to read the processes of investment casting first in order to understand why these machineries are needed. In this article, we’ll explore the various types of investment casting machineries and their functions.

Wax Injection Equipment: The wax injection equipment is used to inject molten wax into the steel or AL mold to form the wax pattern. This machinery includes a wax tank, wax injection nozzle, wax injector, and wax pattern assembly. The equipment should be able to accurately control the temperature and pressure of the wax injection process to ensure consistent and high-quality wax patterns.

Ceramic Shell Production Equipment: The ceramic shell production equipment is used to create the ceramic shell that encases the wax pattern. This machinery includes a shell building station. The equipment should be able to create a strong and durable ceramic mold that can withstand the high temperatures and pressure of the casting process.

Melting and Pouring Equipment: The melting and pouring equipment is used to melt the metal and pour it into the ceramic mold. This machinery includes a furnace, a crucible, a ladle, and a pouring system. The equipment should be able to accurately control the melting temperature and pouring rate to ensure that the metal flows smoothly into the mold and fills all the intricate details of the wax pattern.

Cleaning and Finishing Equipment: The cleaning and finishing equipment is used to remove the ceramic shell and any residual wax from the cast metal part. This machinery includes a shell breaking machine, a shot blasting machine or a sandblasting machine and a grinding machine. The equipment should be able to provide the desired surface finish and dimensional accuracy of the final part.

Quality Control Equipment: The quality control equipment is used to verify that the final part meets the required specifications. This machinery includes various measuring tools such as a coordinate measuring machine (CMM) or a 3D scanner, a surface roughness tester and a metal composition analyzer. The equipment should be able to accurately measure the dimensions, chemical composition of the metal and surface finish of the final part to ensure its quality.

Other than the machineries mentioned above, an investment casting foundry still needs some other equipment such as dewaxing furnace, cutting machine, grinding machine, dust remover machine and more. Investment casting machineries are crucial components of the investment casting process. They play a significant role in determining the quality and consistency of the final product. By using high-quality machineries and maintaining them properly, investment casting foundries can produce high-quality metal parts that meet the demanding requirements of various industries.
