TIPS WITH TONY: Machining Capabilities for High Performance Parts

Do you know how machining a part from titanium can improve its functionality and performance? How about using key inserts for improved durability to your part. Here are few capabilities and design options to keep in mind for your next machined part.

Titanium machined parts.

Titanium
Let’s start off with some big news. Previously, we only offered titanium for 3D-printed parts, but it’s now available to customers for machined parts. And, if that wasn’t enough to catch your attention, how does titanium machined parts in as fast as three days sound?

Titanium is extremely strong and boasts a high strength-to-weight ratio. It also has excellent corrosion resistance, high operating temperatures (up to 1,000°F) and is nontoxic.

Titanium has range of applications due to its advanced material properties. Frequently, you’ll find titanium parts in the aerospace, medical, military and marine industries. More specifically, it’s used for parts like rotors, compressor blades, hydraulic systems, surgical equipment, dental and orthopedic implants as well as in military aircrafts due to excellent ballistic characteristics.

The only drawback is the cost of the raw material. It’s more expensive than steel. For this reason, most manufacturers don’t hold a lot of inventory, but that isn’t the case at Proto Labs. We maintain a level of inventory that allows for on-demand milling and turning of titanium parts

Key insert for added durability.

Key Inserts
Key inserts are steel threaded inserts commonly used in aluminum parts for added durability. Note that these are different from standard coil inserts as they have an added keyway with a tab inserted to prevent twisting under extreme load.

Key inserts are primarily used by the aerospace and military industries following the military standard of MS51835B. We offer eight thread sizes ranging from #8-32 to ½-13. For a full list, visit our threading page and click the key inserts tab.

THE SHORT LIST: 4 New Capabilities at Proto Labs

The crew at Protoworks (our R&D program) has been busy. Every day they’re pushing the boundaries to advance new rapid manufacturing processes and materials and expand your design possibilities.

We just rolled out a few new capabilities that we’re excited to share.

2 is better than 1: Overmolding

Overmolding expands on our injection molding offering. At Proto Labs, it’s a multi-step process where we mold a substrate part and place it into a second mold, which then molds another material onto the substrate. It’s called pick-n-place molding.

Overmolding can aid in dampening vibration, improving grip as well as two-color aesthetics. We are still in the beta testing phase of our overmolding process, but it’s open to everyone.

Extra-strength machined parts: titanium

You asked. We listened. Our CNC machines can now mill and turn parts from titanium. With an excellent strength-to-weight ratio and corrosion resistance, titanium is most suitable for applications in aerospace, medical and other industries where high performance is critical.
