6 Tips for Tackling Complex Features in Moulding Design

Mould-making techniques make complicated features like o-ring grooves, mushroom studs, and text on parts possible

Injection Molding

- manufacturing systems

Designing an injection-moulded part with the proper draft, wall thicknesses, radii, and other considerations can be complicated in itself, so when unique features like bayonets and gears are integrated into your geometry, another layer of complexity can arise. If your part requires intricate features, we’re often able to manufacture them through the use of side-actions, sliding shutoffs, pickouts, and other moulding methods. Here are some of the more commonly found complex features, and how they’re achieved.

Within the blue section of this Torus design aid from Protolabs, various clips and bayonets are illustrated.

Bayonet Mounts

Our capabilities allow for internal bayonet features in part design, which are created using relief holes and a sliding shutoff. The shutoff forms an internal through-hole in a part by bringing the A-side and B-side in contact, preventing the flow of resin into the through-hole. Protolabs requires at least 3 degrees of draft on bayonets.

O-Ring Grooves and Mushroom Studs

If you design a bayonet that contains an O-ring groove, Protolabs will use a two-piece pickout. A pickout is a detachable part of the mould that is manually inserted into the mould prior to the injection process and manually removed from the part after ejection (before the next cycle begins). An O-ring feature can also be made using two side-actions depending on its orientation, proximity to the parting line and freedom from interference from other features. Additionally, we support geometries that contain mushroom studs; those features are achieved similarly to O-rings, with a two-piece pickout or two side-actions. Note that with two-piece pickouts, there will be a witness line where they come together.

Text on Parts

Text on parts is used for different reasons, and if your design requires it, we typically recommend that it be raised above the part versus recessed int

Insight: Plastic Injection Moulding - Improving Part Design with Uniform Wall Thickness

Transcript

Hello and welcome to Proto labs' Insight video series.

Today we’re going to be looking at how you can improve the design of your parts by taking advantage of one of the fundamentals of plastic injection moulding – maintaining uniform wall thickness.

If you want to see this principle in action, all you need to do is pick up pretty much any mass-produced plastic part, like a toothbrush holder or a washing-up tray. Take a good look at it and you’ll see that while the design might have plenty of curves and angles, the walls are almost certainly a relatively uniform thickness throughout.

Why do manufacturers do this?

Well, because if they ignore it that can lead to sinking, warping, inaccurate or non-functional parts. As you may have guessed, these are all bad things that we want to avoid wherever possible.

However, not every product out there is as simple as a tray or a cup. Sometimes the functional requirements of consumer, medical, aerospace, and industrial products leave you with little room to manoeuvre when it comes to wall thickness.

In this case there are two things we need to consider. One: how can we try and keep the walls relatively uniform despite a complex design? And two: what’s the best material for us to work with?

Before we start talking this through, let’s try and define what ‘relatively uniform’ really means in a practical sense
