From Your Drawing to a Finished Component
At Daji, we manufacture precision investment castings according to customer drawings, 3D models, material specifications and application requirements. Our engineering team evaluates the component geometry, material, wall thickness, dimensional tolerances, machining allowance, heat treatment and inspection requirements before production begins.
Engineering Support
Our engineers review manufacturability before tooling and provide recommendations on casting structure, tolerance feasibility, machining allowance and process optimization.
Flexible Production
Support for prototypes, small-batch trials, repeat orders and volume production allows customers to scale projects according to actual market demand.
Custom Manufacturing Capabilities
Drawing-Based Manufacturing
We manufacture directly from customer drawings, 3D models or physical samples and reproduce critical dimensions according to specified tolerances.
Custom Material Selection
Carbon steel, stainless steel and alloy steel are available across a wide range of grades according to strength, corrosion, wear and temperature requirements.
Tooling & Pattern Development
Metal tooling can be developed for repeat production, while rapid prototype routes can be used during early-stage design verification.
Heat Treatment
Normalizing, annealing, quenching and tempering, solution treatment and other heat treatment processes can be selected according to material and performance requirements.
CNC Machining
Turning, milling, drilling, boring, tapping and precision finishing are available for semi-finished or fully machined components.
Inspection & Testing
Dimensional inspection, chemical analysis, mechanical testing and NDT can be arranged according to customer drawings and component requirements.
From Drawing to Serial Production
A successful custom casting project depends on more than producing the first sample.
Our OEM workflow is designed to control technical feasibility, tooling development, material performance, dimensional consistency and batch stability throughout the complete project.
Need OEM Casting Support?
Drawing & Requirement Review
We review drawings, materials, tolerances, quantities and technical requirements to confirm casting feasibility before production.
DFM & Technical Proposal
Our engineers evaluate part geometry, wall thickness, machining allowance and casting risks, then provide practical manufacturing recommendations.
Tooling & Prototype Development
We develop suitable tooling or prototypes to verify the design, dimensions and production feasibility before batch manufacturing.
Casting & Process Validation
Key casting processes are controlled and validated to ensure stable dimensions, surface quality and internal consistency.
Heat Treatment & CNC Machining
Heat treatment, CNC machining and finishing are carried out according to drawing and performance requirements.
Inspection & Batch Delivery
Finished parts are inspected against agreed standards before moving into stable repeat production and batch delivery.
Engineering Support Throughout Your Project
Custom manufacturing requires continuous coordination between design, casting, machining, quality and delivery.
Our engineering and project teams work together from the initial drawing review through sample approval and serial production. Technical requirements are translated into controlled manufacturing parameters, while project progress and quality feedback are communicated throughout the production process.
For repeat OEM programs, process records and inspection requirements can be maintained to support stable long-term supply.
