Foundry Hand Tools — Confirm the Function of a Slick In manual mould making and finishing, is a slick used for repairing imperfections and finishing the mould surface prior to closing the box?

Introduction / Context:
A slick is a flat, smooth-bladed foundry tool used during mould finishing. Clear understanding of common hand tools helps maintain surface quality and reduce rework in green sand moulding.

Given Data / Assumptions:

• Moulds are prepared in cope and drag using green sand.
• After ramming and pattern withdrawal, minor surface flaws may remain.
• Objective is surface correction without damaging edges or draft.

Concept / Approach:
The slick’s flat, polished surface allows gentle scraping and smoothing to repair small tears, scabs, and scratches. It is especially useful for finishing corners, fillets, and shallow depressions so that the casting surface reproduces accurately and requires minimal fettling later.

Step-by-Step Solution:
Identify defect after draw (e.g., small breaks or roughness).Use slick to smooth and restore intended geometry.Brush off debris and lightly dust with parting if needed before closing.

Verification / Alternative check:
Foundry manuals list slicks and trowels as finishing tools distinct from gating tools and rammers.

Why Other Options Are Wrong:
Gate cutting uses gate knives or lifters, not slicks.Ramming uses peen and butt rammers; slicks are not ramming tools.Limiting slicks to cores is incorrect; they are used on moulds as well.

Common Pitfalls:
Over-smoothing can close intended vents or alter dimensions; finish lightly and check with gauges.

Final Answer:
Correct
