Quality Control at Every Step
At Hollingsworth, Quality is the heart of our focus. While we know a supplier can’t be everything to everyone, we make it our first priority to consider every customer’s machined part with the highest regard. This means if we produce your product, we expect to produce exactly what you want and need.
Certainly, it’s impossible to be perfect, but we’re not boasting when we say we expect your parts to be perfect… it’s simply our business philosophy.
Hollingsworth machined products meet the standards Americans expect. Our parts are made from material primarily produced in the United States. This eliminates many of the problems you find from imported products like brass fittings from China that have porosity issues or overseas material that doesn’t meet strict U.S. standards.
Our plating process is just a few miles from our shop and painted products get done right here in Marshalltown.
It is our mission to provide customers with U.S. manufactured and machined components that always meet America’s standards for safe and long lasting products.
Certified Material
When it comes to quality, you have to start with good material. All material Hollingsworth Mfg. purchases requires a certificate of material.
This provides us with the Heat Lot and Material Specifications for every bundle we buy.
Our suppliers like Earle M. Jorgenson, Crucible Metals, or Central Steel & Wire provide us with this documentation with every delivery.
Any excess material or material purchased for inventory is tagged with the Material Certs identifying grade, source, and heat lot numbers for traceability.
Customers who provide castings are expected to certify or inspect the raw castings for quality approval.
Quality Inspection During Production
At Hollingsworth, we inspect parts at the source of production. Developing production processes involves understanding not only the prints but also how the parts are used, handled, stored, and shipped.
Surface finish requirements are noted and critical dimensions are inspected during manufacture.
At each stage in production we maintain a detailed logbook tracking tooling changes, offset adjustments, inspection results, and production notes.
Our inspection process is batch-based. Parts are inspected as they are produced rather than waiting until the entire run is complete.
If an issue is found, the batch is isolated, the problem is corrected, and the parts are individually inspected.
If required by the customer, we maintain inspection reports coded to each purchase order and delivery.
