Casting Dimensions, Weights & Tolerances Explained
At Texmo Blank, precision is paramount in delivering high-quality investment castings that meet the stringent requirements of complex industries.
Our advanced casting processes enable us to produce detailed, intricate parts while ensuring precise casting dimensions, weights, and tolerances. Accurate measurements are crucial for making parts that fit perfectly, perform reliably, and minimise costly post-casting adjustments.
Casting Dimensions: Size Capabilities and Importance
Our investment casting process supports a wide range of casting dimensions, accommodating everything - from tiny, intricate components to large, robust parts.
- Minimum size: 5 x 5 x 5mm
- Maximum size: 600 x 600 x 600mm
Precise casting dimensions ensure that the parts will integrate seamlessly into assemblies, reducing delays and additional machining costs. Texmo Blank’s expertise enables us to maintain consistent dimensional accuracy across large and small castings, supporting high-performance applications in aerospace, automotive, medical implants, industrial machinery, and more.
Casting Weights: Versatility from Light to Heavy Components
Our casting process handles a broad spectrum of casting weights, matching project needs for lightweight precision or heavier-duty parts.
- Minimum weight: 2 grams
- Maximum weight: 25 kilograms (or higher with specific arrangements)
This weight capability versatility allows us to serve diverse industries with parts optimised for strength, weight, and performance, while maintaining exacting casting standards.
Casting Tolerances: Why Precision Matters
Tight casting tolerances are crucial for minimising machining time, enhancing product quality, and ensuring that parts meet exact functional requirements. At Texmo Blank, our investment casting process consistently delivers tight tolerances, typically within 1% of the nominal casting dimension, which helps avoid costly rework.
Our typical casting tolerances depend on part size, complexity, and range according to international standards, supported by advanced ceramic shell moulds for smooth finishes and dimensional accuracy. For parts requiring even tighter precision, secondary finishing processes such as CNC machining and grinding are available.

Why Accurate Casting Measurements Are Critical
Achieving precise casting dimensions, weights, and tolerances is crucial in industries that require high-performance parts. Texmo Blank’s state-of-the-art technology and quality controls ensure:
- Consistent Quality – Every casting strictly adheres to client specifications and industry standards.
- Reduced Secondary Work – Tight tolerances require less machining or finishing.
- Design Possibilities – Precision casting unlocks the door to complex geometries and innovative product designs.
Frequently Asked Questions about Casting Dimensions, Weights & Tolerances
What are typical tolerances for investment castings?
Typical casting tolerances vary depending on the part size and complexity, but generally achieve a tolerance of ±0.25 to ±0.5 mm (±0.01 to ±0.02 inch). Tighter tolerances can be achieved with secondary machining if required.
How important are casting dimensions in manufacturing?
Accurate casting dimensions are crucial for ensuring that parts fit and function correctly within assemblies, thereby reducing costly delays and rework in later production stages.
Is there a weight limit for investment castings?
While we commonly produce castings up to 25 kg, larger or heavier parts can be accommodated with special arrangements to meet specific project requirements.
