Application Guide

Removing Stamping Oils and Forming Lubricants from Metal Parts

Stamped, drawn, and formed metal parts come off the press coated in lubricant — compounds designed to cling to metal under extreme forming pressure. Before welding, powder coating, plating, or assembly, every trace of this lubricant must be removed. Inadequate cleaning causes weld porosity, coating adhesion failures, and assembly contamination. Magido aqueous parts washers are built to handle this cleaning task at production volume.

Why Stamping Lubricants Are Difficult to Remove

Stamping and forming lubricants are engineered for adhesion — they must maintain a film under pressures that exceed the yield strength of the metal being formed. Straight oils, sulfurized oils, chlorinated compounds, and water-soluble forming fluids all present different removal challenges. Simply rinsing with water is ineffective.

Aqueous cleaning addresses this with the combination of heated detergent solution (chemical action), temperature (thermal energy to mobilize oil films), and mechanical spray or agitation (physical displacement). This three-way attack removes forming lubricants that cold-rinse and wipe methods leave behind.

Inline Cleaning for High-Volume Stamping Operations

High-volume stamping operations produce parts faster than any batch washer can clean them. The solution is an inline belt conveyor washer that integrates directly into the part flow after the press or blanking line.

Magido's Gold and Silver series conveyor washers carry stamped parts through wash and rinse zones continuously on a stainless steel mesh belt. No batching, no operator intervention between parts, no production bottleneck. Belt speed, wash temperature, and detergent concentration are all adjustable to match the lubricant type and part geometry.

Batch Cleaning for Job Shop and Mixed-Part Operations

Stamping job shops and contract manufacturers deal with mixed parts, varied lubricants, and changing production schedules. A single inline washer cannot cover this variety — batch washers are the right tool.

Magido's top-load spray cabinets (X51, X81 series) handle mixed batches of stamped parts in a basket, cleaning all surfaces in a single automated cycle. For parts with complex geometries or formed features that trap lubricant in recesses, Magido's immersion washers provide thorough cleaning through full submersion and agitation.

Pre-Treatment Cleaning for Coating and Welding

Parts destined for powder coating, e-coat, plating, or painting require a surface that is chemically clean — not just visually clean. Residual forming lubricant under a coating creates adhesion failure, blistering, and corrosion. The same standard applies before welding: oil contamination in the weld zone causes porosity, spatter, and weakened joints.

Magido's aqueous washers, using appropriate detergent chemistry and sufficient wash temperature, deliver the surface cleanliness that coating and welding operations require. The AISI 304 stainless steel construction ensures no contamination is introduced by the washer itself.
