Precision Cleaning Chemicals for General Engineering & Metal Components Manufacturing
Every Metal. Every Process. Every Application.
- INDUSTRY OVERVIEW
General Engineering and Metal Fabrication — The Backbone of Indian Manufacturing
India’s general engineering and metal components sector is vast, diverse and fundamental to the country’s industrial economy. Spanning thousands of small, medium and large manufacturers across every industrial cluster in the country — this sector produces the components, sub-assemblies, fasteners, forgings, castings, machined parts and fabricated structures that feed into virtually every downstream manufacturing industry.
From precision machined components for industrial machinery and equipment to fabricated structural steel, pump and valve components, agricultural equipment parts, electrical fittings, hardware and general metal products — the general engineering sector encompasses an enormous range of manufacturing processes, metal types and cleanliness requirements.
What unites this diverse sector is a common set of cleaning challenges — removing machining oils and coolants, preventing inter-process rust formation, preparing surfaces for painting and coating, maintaining cutting tool performance, and keeping manufacturing facilities clean and safe.
REFA Chemical Industry supplies a comprehensive range of precision cleaning, surface treatment and process chemicals to general engineering and metal component manufacturers across India — providing the right chemical solution for every metal, every process and every application.
Whether you manufacture pumps, valves, fasteners, forgings, castings, machined components, structural fabrications, agricultural equipment, electrical fittings or general metal products — REFA has the cleaning and process chemical solution your operation needs.

Cleaning Challenges We Solve Every Day
Machining Oil and Coolant Residue
Cutting oils, coolants and machining fluids remain on component surfaces after machining operations — preventing adequate paint adhesion, causing plating failures and creating quality issues in subsequent processes. REFA Solution: REFA precision degreasers for mild steel, cast iron, aluminum, stainless steel and brass remove all machining oil and coolant residues completely — leaving surfaces clean and ready for the next production process.
Inter-Process Rust Formation
Mild steel and cast iron components develop rust during storage between machining and surface treatment — causing rework, material rejection and production delays. REFA Solution: REFA rust preventive additives and temporary corrosion protection chemicals provide inter-process rust protection — keeping components rust-free during storage and transit between production stages.
Forging and Casting Scale Removal
Hot forgings and castings carry thick oxide scale that must be removed before machining or surface treatment — standard cleaning chemicals are ineffective against this type of contamination. REFA Solution: REFA rust cleaner and descaling chemicals effectively remove forging scale, casting sand and oxide deposits — preparing surfaces for subsequent machining or surface treatment processes.
Pre-Painting and Pre-Coating Surface Preparation
Paint adhesion failures and coating defects traced back to inadequate surface preparation — contaminated or oxidized surfaces that prevent proper bonding of paint or coating. REFA Solution: REFA complete surface preparation range — degreasing, rust cleaning, phosphating and passivation — ensures perfectly prepared surfaces for maximum paint adhesion, powder coating and plating quality.
Pre-Plating Surface Preparation
Plating — zinc, nickel, chrome or other metal plating — requires absolutely clean, contamination-free base metal surfaces for proper adhesion and uniform plating deposit. REFA Solution: REFA precision degreasers and surface preparation chemicals deliver the ultra-clean, activated metal surfaces required for successful plating operations — eliminating adhesion failures and plating defects.
Cutting Tool Performance and Coolant Management
Poor cutting fluid performance causes premature tool wear, surface finish problems, dimensional inaccuracy and operator health issues from contaminated coolant. REFA Solution: REFA cutting fluid range — water-based and oil-based — provides optimal lubrication and cooling for all standard machining operations — extending tool life, improving surface finish and maintaining a healthy coolant system.
