BUILD-A-
PART®
Affordable Unique Solutions:
Design Your New Component with Build-A-Part®
Bondable Components!
Component designers
no longer need to
be constrained
by the limitations
of injection molding
tool design. The exact
fitting, in the optimal layout
for the process or product
concept, is now available with
Value Plastics’ line of Build-a-Part®
bondable components, designed for use with
gases or liquids.
The Build-a-Part® system is based on combining
interchangeable components, joining junction blocks and
luers, hose barbs or threaded features to create the desired
configuration. The features are bonded to the junction blocks
using commonly available adhesives. Junction blocks and
features may be bonded together to create multi-port, multi-
axis products that receive and redirect fluid flow in whatever
direction the designer desires. The only limitation is the
designer’s imagination.
114 component options are available from stock in two
primary materials. Options include ISO 594-1 compliant male
and female luers and hose barbs in 1/16” (1.6 mm), 3/32” (2.4
mm) and 1/8” (3.2 mm) in straight, elbow and branch tee
configurations. Also available are male threads including 10-32
UNF, 1/16-27 NPT, 1/8-27 NPT, 1/4-28 UNF and M6x1 versions,
and mounting devices.
The complete range is available in two primary resins: white
ABS or translucent polysulfone. For ease of testing concepts,
Value Plastics offers designer kits in both resins. Each kit
contains hundreds of components for prototype purposes,
enabling designs to be created and modified prior to
production commitment.
Bonding Suggestions
Prior to actually bonding, press together a model of the
manifold to use as a reference.
Do not mix plastic resins. Consult your adhesive specialist if
you need to bond dissimilar materials.
These components are designed for bonding with any one
of a number of solvents, but other adhesive systems may be
used. When solvent bonding, use a very small gauge needle
(typically 27 or 30) for best solvent control. Consult your
adhesive specialist for guidance on other systems.
Apply solvent sparingly. Most solvents are low viscosity
and readily wick into the bondline. Excessive solvent may
compromise the aesthetics and the function of the assembly.
Press the mating components together leaving a .01-.03” gap
between them for the solvent. Place the components in an
orientation such that they may be rotated ¼ turn to their final
position after applying the solvent.
After applying solvent, wait a few seconds, then rotate the
components to their final position. When making a long
manifold with bondable junction blocks it may be helpful to
push the assembly against a flat surface to align the blocks
before the solvent has set.
