# Process Comparison

*Eliminating multiple processes to achieve a desired geometry means eliminating additional cost and waste to make the smallest, most complex parts at high volumes with faster lead times.*

Titanium Injection Molding is capable of creating complex components through a [seamless process](https://praxisti.com/technologies/titanium-injection-molding/process-description?hsLang=en). Small, complex geometries that require a large volume of material to be removed via multi-axis CNC machining are ideal candidates for Titanium Injection Molding. Other manufacturing processes such as machining, investment casting and conventional PM are unable to produce thinner wall sections, holes and threads without multiple steps.

## *Compare Praxis’ Titanium Injection Molding technology to other manufacturing methods:*

| Attribute | Titanium Injection Molding | Conventional Press & Sinter | Machining | Investment Casting |
| --- | --- | --- | --- | --- |
| **Density** | +99% | 88% | 100% | 98% |
| **Tensile Strength** | High | Low | High | High |
| **Elongation** | High | Low | High | High |
| **Hardness** | High | Low | High | High |
| **Complexity** | High | Low | High | Medium |
| **Surface Finish** | High | Medium | High | Medium |
| **Production Volumes** | High | High | Low | Medium |
| **Range of Materials** | High | High | High | Medium-High |
| **Cost** | Medium | Low | High | Medium |

| Conventional Powder Molding | Machining | Investment Casting |
| --- | --- | --- |
| Titanium Injection Molding can produce geometries that **eliminate secondary operations** | Titanium Injection Molding **designs save material and weight** | Titanium Injection Molding can **produce thinner wall sections** |
| Titanium Injection Molding can **combine** two or more PM **components** into one, **reducing part count** | Titanium Injection Molding provides **cost savings through better material utilization** — sprues and runners can be reground and reused as feedstock with no compromise to final properties | Titanium Injection Molding produces **better surface finish**, **higher complexity** and **greater production volumes** |
| Titanium Injection Molding offers: superior density corrosion performance strength ductility elongation hardness | Molding from a single tool **eliminates multiple set-up operations** | Titanium Injection Molding is **better for small-diameter blind and through holes** |
|   | **Difficult-to-machine **materials can be **molded** **into a net shape** | Titanium Injection Molding greatly **reduces requirements for finish machining** |
|   | Higher production volume | Titanium Injection Molding produces **high volumes of small components** at a **lower cost**, **faster lead times** |

## Which Features are Suitable for Titanium Injection Molding?

Although versatile, Titanium Injection Molding has ideal design characteristics to determine whether or not something is best suited for Titanium Injection Molding. Below is table that outlines what Praxis believes to be desirable, allowable and the aspects that should be avoided when considering Titanium Injection Molding:
