A kitchen mandoline is a stainless steel plate and blades, plus everything that holds it together, guides the hand and protects the fingers: plastic parts that must be stiff, accurate and pleasant to handle.
For a French kitchenware manufacturer, we moulded the plastic parts of a stainless steel mandoline: two side rails and the end grip.
The parts
- two side rails, left and right, about 384 mm long, forming the frame;
- four stainless steel inserts integrated into each rail, taking the plate fixing screws;
- an end grip of about 100 mm, the roller you hold the mandoline by while slicing.
A long part is a real challenge
A plastic rail of almost 40 cm leaves no room for error. If it warps while cooling, the plate no longer lines up and the blade cuts unevenly. It takes a balanced mould, even filling along the whole length and controlled cooling. The inserts must also sit precisely in the mould so the screws line up after assembly.
Why stainless steel inserts
A 316L stainless insert gives a durable metal thread that resists dishwasher and salt-water corrosion, where a thread cut straight into plastic would wear over time.
