The established range of HI-BAR® Safety
Screens available from miniature component
specialists THE LEE COMPANY now includes
an insert retained option for high pressure
applications. The new HI-BAR screen design
option offers the key performance advantages
created by Lee’s unique drilling techniques
along with the installation and retention
benefits associated with the insert locking end.
Acknowledged as pioneers in miniature
fluid control, Lee’s HI-BAR safety screens are
widely used to protect critical components
in both liquid and pneumatic systems in high-
technology applications such as aviation, oil
and gas exploration and other similar systems.
The key features and benefits of the new
screen include; simple and direct installation
into fluid passageways with a field-proven
locking end, stainless steel construction,a strong, one-piece screen element and
a burst / collapse pressure rating up to
7500 psid. They provide effective and
proven protection for critical components
such as valves, nozzles and orifices from
contamination. They also ensure additional
levels of protection on sub-system
components such as pumps, flow dividers,
gearboxes, actuators and control valves.
They are available in 4 different bodydiameters of 4.74mm, 6.35mm, 9.52mm
and 12.7mm. Standard screen hole sizes
include 50, 75, 100, 150, 200, 250, 380
and 500 microns. In addition to their
suitability to aviation, aerospace and motor
racing applications their excellent corrosion
resistance to a variety of media, means they
are also ideal for use in marine, medical and
oil industry applications.

A precision-engineered replica model of a
‘smart bin’ aimed at cutting food waste has
helped an aspiring designer and entrepreneur
showcase his product to potential customers.
The intelligent food waste container
designed by Daniel Lloyd is aimed atrevolutionising the way businesses, local
authorities and members of the public use their
bins – dramatically reducing the amount of food
needlessly thrown away each year.
His start-up design consultancy, Daniel By
Design, approached Hertfordshire-based Ogle
Models to consult on, and complete the finalsemi-functional prototype.
The project required precise finishing as well
as functionality within the lid movements, both
within a tight timescale. Initially, CAD designs
of the wall thickness were altered to avoid
potential breaking due to excessive deflecting
under load.
The entire project was built using the
SLA Ipro 8000 as the bed size (650 x 750
x 550 mm) allowed for all parts to be built
at once, reducing lead times. SLA was also
the preferred process due to the relative
ease of finishing and the ability to print crisp
lines and the specific features required for
the project.
The waste system works by using
technology enabling four outside waste
containers to report daily on volume and mass
of waste. The bins also feature ventilation units
and carbon filters so that, if the containers are
not due to be collected for a month, odours
are reduced.
