Our Quality Management System
Roll-Fast has a complete Quality Lab staffed with experienced technicians to guarantee you receive the highest quality fasteners & Components for each order.
Our quality assurance process assures that we have the capability to perform testing to standard, special print, and customer-specific requirements. Our Integrated Quality Systems include in-process inspection, including visual and machine sorting, as well as Statistical Process Control data collection to monitor quality and production reliability. Final inspection and testing verify production quality.
Our promise to you: We make continuous improvement and total quality management the highest standard among our manufacturing locations.
Quality assurance and testing are the most important part of fastener & components manufacturing. At our company we incorporate the best test methods to analyse the fastener & components and give a quantitative analysis of the bolt with supportive evidence in form of elaborate test results.
Quality assurance (QA) is any systematic process of determining whether a product or service meets specified requirements. Quality assurance can be defined as "part of quality management focused on providing confidence that quality requirements will be fulfilled. QA establishes and maintains set requirements for developing or manufacturing reliable products.
- Failure testing, which continually tests a product to determine if it breaks or fails. For physical products that need to withstand stress, this could involve testing the product under heat, pressure or vibration.
- Statistical process control (SPC), This methodology uses statistical methods to manage and control the production of products.
- Total quality management (TQM), which applies quantitative methods as the basis for continuous improvement. TQM relies on facts, data and analysis to support product planning and performance reviews.
The Quality control involves testing units and determining if they are within the specifications for the final product . The purpose of the testing is to determine any needs for corrective actions in the manufacturing process. Good quality control helps companies meet consumer demands for better products.
Or, The process to verify whether the products are manufactured correctly as per design & standard specified for it.
Quality Control Instruments
- Model : Magnetic crack detector, model UNIMAG UCH 310
- Make : NDTA, Kolkatta
This method is used for the detection of surface and near-surface flaws in ferromagnetic materials and is primarily
used for crack detection. The specimen is magnetised either locally or overall, and if the material is sound the magnetic flux is predominantly inside the material. If, however, there is a surface-breaking flaw, the magnetic field is distorted, causing local magnetic flux leakage around the flaw. This leakage flux is displayed by covering the surface with very fine iron particles applied either dry or suspended in a liquid. The particles accumulate at the regions of flux leakage, producing a build-up which can be seen visually even when the crack opening is very narrow. Thus, a crack is indicated as a line of iron powder particles on the surface.
To check surface cracks in critical Automotive Components, Bolts for wind energy, Solar plants, Aerospace etc.
- Model : Elektra
- Make : MeeraMetzer, India
Profile projectors (optical comparators) are a type of optical measuring instrument. The measurement principle is similar to that of optical microscopes. The target is placed on the stage, and a light is shined on the target from underneath. This causes the target's profile, or shadow, to be projected on the screen. Equipped with latest DRO software for measuring dimensions 1 micron least count scale.
- Model : 178-923E SJ210
- Make : Mitutotyo, Japan
A roughness tester is used to quickly and accurately determine the surface texture or surface roughness of a material. ... A roughness tester shows the measured roughness depth (Rz) as well as the mean roughness value (Ra) in micrometers or microns (µm).
We can check the Least Count: 0.001mm (1 Micron) .
- Model : Coat measure-C & more..
- Make : Coat measure, Precise India
A coating thickness gauge (also referred to as a paint meter) is used to measure dry film thickness. Dry film thickness is probably the most critical measurement in the coatings industry because of its impact on the coating process, quality and cost.
Measures the thickness of Non-magnetic coating on magnetic base. The coating may be of materials like: as, Copper, Zinc, Tin, Chromium, Hard Chromium, Lead, HDG, Geomat, Zinc flake etc.
Laser Marking Machine
Laser marking works by using a focused beam of light to mark the surface of a material . When the beam interacts with the material's surface, it alters the material's properties and appearance. We have in house facility of laser marking. We can do laser marking any type of product.
Pneumatic dot peen marking
The Dot Peen marking or engraving is a process pin marking application that make deep, permanent impressions in a variety of materials for identification and traceability . We use dot peen marking on Studs, Bolts, Nuts, Components etc. We can do marking in any shape, alphabet, design as per your need.
Instruments & Gauges
We have wide range of instruments for quality control system like, Digital Hight gauges, Digital Vernier calipers, Manual Vernier calipers, Digital Micrometer, Manual micrometer, Plug gauges & Ring Gauges for Inch & metric series sizes, Filler gauge, thickens gauge, Angle gauge, Dial gauge, radius gauge etc.
