Heat Set inserts are installed by heating process. Generally, the heat is applied to insert part through soldering iron or similar heating tools. For larger inserts a wide heating tip is used.
Heat set inserts are best for creating strong threads in plastic parts especially thermoplastics. During the installation thermoplastic melts and reflows around the insert part. This way the insert part makes a strong bond with the plastic body.
Brass heat-set inserts are commonly used in a wide range of industries and applications. Brass heat-set inserts provide reliable threaded connections in materials that may not have inherent strength for direct threading. Brass Heat-Set inserts are designed to be heated and then pressed or screwed into the host body and embedded permanently. Heat-set inserts are perfect for thermoplastics in 3D printing because during installation the thermoplastic melts and reflows around the insert.
The insert design depends on the bolt or thread size (Mx). In typical design the insert length(L) is approximately 1.9x, the outer diameter(D1) is 1.5x to 1.55x and the installation tip(D2) is 1.28x to 1.32x. The plastic body hole diameter is approximately 101% of the installation tip (D2). And the minimum wall thickness should be greater than 0.52x. Let's understand the design parameters for M3 insert.
Length (L) : 1.9x = 5.7mm
Outer Dia (D1) : 1.53x = 4.59mm
Installation tip (D2) : 1.3x = 3.9mm
Hole Size(D3) : D2 x 1.01 =3.95mm
Min Wall Thickness(W) : > 0.52x > 1.56mm
This is method works on most common plastics. However, actual design may vary depending on the body material properties and strength requirements.
