MANUFACTURING SOLUTIONS & PROCESS OPTIMIZATION
Better Manufacturing Solutions for Custom Cast, Forged & CNC Machined Components.
We help industrial OEMs develop better manufacturing solutions from drawing to finished part — optimizing process flow, material usage, tooling and machining, while integrating multiple manufacturing processes into one coordinated route. In most past projects where optimization was applied, manufacturing costs were reduced by 10–30% while fully maintaining the required quality and inspection standards.

01 / MANUFACTURING CAPABILITIES
Five Manufacturing Routes. One Part-Focused Decision.
Investment casting, sand casting, die casting, forging and CNC machining solve different problems. We review geometry, alloy, volume, tolerances and finished-part requirements before deciding which route makes the most sense.
01
Investment Casting
Discover high-precision, near-net-shape components with intricate geometries and excellent surface finishes.
View Capability →
02
Sand Casting
Ideal for large, heavy-duty metal components with flexible production volumes and cost-effective tooling.
View Capability →
03
Die Casting
Efficient high-volume production delivering durable, thin-walled parts with tight tolerances and smooth surfaces.
View Capability →
04
CNC Machining
Achieve extreme precision, tight tolerances, and custom geometries for both quick prototypes and production runs.
View Capability →
05
Forging
Engineered for maximum mechanical strength, fatigue resistance, and structural integrity under high-stress applications.

02 / ENGINEERING FIT
Can We Manufacture Your Part?
We do not start by asking which process you want. We start with what the part needs to do.
Geometry, material, production volume, critical features, tolerances and secondary operations all affect the manufacturing route. Send the drawing first so the process can be reviewed around the part instead of forcing the part into a predetermined method.
MaterialCarbon steel, stainless steel, alloy steel, aluminum and other engineering alloys
GeometryComplex castings, structural components and precision-machined metal parts
Size & WeightReviewed according to the actual drawing, alloy and selected process
ToleranceCritical dimensions and machining allowances evaluated before production
SurfaceMachining, polishing, blasting and specified finishing routes
VolumePrototype, small batch and repeat OEM production can be assessed

05 / ABOUT TIANHUI MACHINE
Manufacturing Support Built Around the Part, Not Just the Process.
TIANHUI MACHINE supports drawing-based metal components through coordinated manufacturing across investment casting, sand casting, die casting, forging and CNC machining.
With manufacturing activities in Ningbo and Chizhou, forming, machining, heat treatment, finishing and inspection can be reviewed as one finished-part route. Our focus is not simply choosing a process, but developing a stable manufacturing solution around the actual part requirements.

About Our Factory
06 / QUALITY CONTROL
Inspection Is Planned Into the Production Route.
Material, process, dimensions and final condition are checked at the stages where they matter. This makes quality control part of production rather than a last-minute inspection step.
View Quality ControlMaterial Verification
Confirm specified grade and incoming material requirements before production.
Process Inspection
Check critical manufacturing stages before defects move into later operations.
Dimensional Inspection
Measure finished features against drawings and defined tolerance requirements.
Final Verification
Complete appearance, documentation and release checks before shipment.
07 / CASE STUDIES
