Frequently Asked Questions
Everything you need to know before working with HDC Manufacturing.
What is open-die forging, and what application is it suitable for?
Open-die forging is a metal forming process in which heated metal is shaped using compressive forces without being fully enclosed in a die. It is particularly suitable for producing large, high-strength components, custom shapes, and low-volume parts.
Common applications include heavy-duty shafts, rings, discs, and other critical components used in industries such as energy, mining, heavy machinery, and industrial equipment.
Does HDC provide the open-die forging service in its own facility?
HDC provides open-die forging services through our network of qualified and certified manufacturing partners rather than performing the forging operations in our own facility.
We carefully select suppliers based on their technical capabilities, quality standards, and project requirements to ensure reliable manufacturing solutions.
Is HDC responsible for the quality?
Yes. HDC takes responsibility for quality verification and overall project coordination throughout the manufacturing process.
From initial prototyping to final production, we manage technical challenges, coordinate quality inspections, and oversee additional processes such as machining, heat treatment, and surface finishing when required.
Our value goes beyond sourcing forged parts. We provide comprehensive supply chain solutions, helping you overcome manufacturing challenges and ensuring a smooth process from concept to finished product.
What's the minimum order quantity (MOQ) for open-die forging parts?
The MOQ depends on the size, material, and complexity of your parts. For large open-die forged components, we can accommodate orders as small as a single piece.
Whether you need a one-off custom forging or a larger production batch, feel free to share your requirements with us, and we’ll help you find a practical manufacturing solution.
How do I know if open-die forging is suitable for my project?
You don’t need to figure that out on your own. Simply share your project details with us, including the material, dimensions, technical drawings, and intended application.
Our team will evaluate your requirements and recommend the most suitable manufacturing process, whether that’s open-die forging or an alternative solution.
Our goal is to help you choose the right manufacturing approach based on quality, cost, and technical feasibility.
