what is custom casting parts
Custom casting parts
Customized casting parts are products that are produced according to the customer's drawings or according to the customer's needs we design drawings and cast according to this drawings.This kind of product production method is more special, need to make the corresponding mold before production.
Features of Custom Casting Parts
Support Any Shape Customization
We have rich experience in casting and can meet any shape of your drawing.We have provided customized parts for Indonesia's tobacco and food packaging machine manufacturers, and have been contracted to cast 90% of the parts for the entire machine.These parts come in a variety of shapes, from monolithic castings to those with complex internal spaces and those that require pre-drilled holes for casting, etc., and we are able to meet the customer's requirements.
Reduction of Material Waste
By melting the material and pouring it into custom casting molds to form specific shapes of cast blanks, it is possible to improve material utilization over CNC machining methods.Because CNC machining is a material reduction process, casting can achieve up to 97% material utilization while CNC machining often results in less than 60% material utilization when producing the same shape.
With Strict Quality Inspection
The customized castings we produce go through a series of quality inspection operations between shipments.For castings of different sizes, we utilize different inspection equipment, such as micrometers, ultrasonic flaw detectors, and CMMs.After ensuring that there are no quality problems, we will spray a layer of anti-rust oil on the castings according to different materials to prevent corrosion on the machined surface due to other factors.
Process And Material Selection
Depending on the quantity of customer's order, we can choose different casting methods, the main casting methods we use are Sand Casting, Lost Foam Casting, Gravity Casting and Investment Casting, among which, we usually choose sand casting and lost foam casting for small production, because these two methods take shorter time to produce.lost foam casting, because these two ways of production time is shorter.If the customer needs casting parts that do not require finishing operations but have to meet a certain casting accuracy and surface finish, we will choose Investment Casting for them.
For material selection, we mainly provide Gray cast iron (HT), ductile iron (QT), carbon steel, stainless steel, aluminum alloy, copper alloy and other materials, with tensile strength covering 200-800MPa. However, the specific material selection will be based on customer's drawing requirements.
applications
Gearbox Housing: The internal structure of these products varies from customer to customer, and can be molded in one piece through customized casting for more efficient production.
Machine Tool Structural Components: Machine tool equipment is generally assembled by a variety of structural components, and these structural components are used in the way of custom casting to produce, because some of the structural components of the weight of a single piece of up to several tons, CNC machine tools can not be directly processed.
Robot Arm Shell: This shell exists in a large internal space for wiring, and according to the different speed reducer used by the robot manufacturer, the shell of the reserved aperture, the overall shape is also different, the use of castings can be very good according to the customer's needs for production.

FAQ
Q: What information do I need to customize your company's castings?
A: We require drawings (if available). We support 2D/3D drawings. We also provide required parameters (if drawings are unavailable), including operating temperature, corrosive media, and mechanical properties. We can design custom drawings based on your needs.
Q: How should I choose a casting process for different order quantities and precision requirements?
A: For small-batch orders (such as trial runs or niche equipment parts), sand casting or lost foam casting are recommended. These processes offer short production cycles, can quickly meet small-batch delivery requirements, and balance efficiency and cost.
For regular batch orders with general precision requirements, gravity casting is recommended.
Q: How do you ensure the quality of custom castings? What testing and protective measures are performed before shipment?
A: Dedicated equipment is used for castings of varying sizes and precisions-micrometers are used to inspect high-precision dimensional tolerances, ultrasonic flaw detectors are used to detect internal defects (such as pores and slag inclusions), and coordinate measuring machines (CMMs) are used for comprehensive precision calibration to ensure that each casting meets requirements.
Factory Preservation: After confirming that there are no quality issues, a customized anti-rust oil is sprayed based on the casting material characteristics (such as carbon steel, cast iron, or aluminum alloy) to prevent damage to the machined surface caused by humidity and environmental corrosion during storage and transportation, ensuring product condition upon delivery.
Q: What industrial components are custom castings primarily used for? What are the key reasons for choosing custom casting for these parts?
A: Currently, the core applications are in three key components, with the specific details and selection reasons as follows:
Gearbox housings: The internal structure of gearboxes varies significantly between customers (such as gear layout and oil circuit design). Custom casting allows for integrated molding, reducing assembly steps, improving housing sealing and structural strength, and making it more suitable for gearbox applications than pre-assembled systems.
Machine tool components: Some machine tool components can weigh several tons, exceeding the direct processing capabilities of CNC machining. Custom casting can overcome weight and size limitations, producing large-scale, integrated components and avoiding the precision errors caused by assembling multiple parts.
Robot arm housings: The arm housings require ample internal space for wiring and must accommodate reducers from different manufacturers (with varying apertures and overall shapes). Custom casting allows for precise matching of these detailed requirements.
Q: Does it support small-batch trial production? What is the approximate lead time for small-batch orders?
A: Small-batch trial production (e.g., trial assembly of dozens or hundreds of units) is clearly supported, and small-batch orders are one of our preferred scenarios. The lead time depends on the complexity of the project. For sand casting or lost foam casting (commonly used for small batches), the typical lead time is 2-4 weeks (including mold making, casting, and testing). For higher precision investment casting, the mold making process is more sophisticated, so the lead time is slightly longer, approximately 3-5 weeks. The specific lead time can be adjusted based on order details (such as part complexity and material type).
Q: If the casting requires subsequent processing (such as drilling or polishing), can we provide one-stop service?
A: Yes, we can. We have a vertical machining center that can perform CNC finishing for custom castings (such as drilling, polishing, and fine-tuning), eliminating the need for customers to work with third-party manufacturers.
