Defining one's own production tolerances is always preferable to accommodating those of sub-contractors. We therefore develop and manufacture tools and forms, all of the molds used in injection molding, as well as the essentials for manufacturing, in our own Tool & Die Department.
Precision has to be more than a one-off achievement, hence the key role of continuously high quality standards during the manufacturing process. This ensures high precision not just once, but a thousand times… so we are able to manufacture products that meet the most stringent requirements – both ours and our clients’.
An example of this is the BETA 200S ophthalmoscope. A closer examination of the manufacturing process involved reveals that no fewer than 74 quality control checks and inspections are performed before the final product is ready. Some find this too costly, but we simply refer to it as HEINE quality.
A guarantee of absolute precision is the underlying essential condition for creating a high quality product. This principle applies to HEINE’s entire production line. Our lenses, for example, are manufactured using numerically controlled machines that rank among the most up-to-date. Many of our lenses are made with ±0.0001 mm accuracy – one twentieth (1/20th) the diameter of a human hair.
