As we have already alluded to our capability to take an idea and make it a reality in a quick and efficient manner in a previous blog, it should come as no surprise that we are highly skilled at every level. In order to better understand just what we do at each production step, here is a complete breakdown of our manufacturing process:
Stage 1: Prototyping
At times as a first step, we get requests from client for prototyping work. With our in-house 3D printer, we take the design and print it out for the customer – according to their drawing and specifications. Then the customer can take the printed prototype and “interference fit” it into the assembly, to make sure it performs the job that they want it to do.
Harvan will sometimes find issues with the drawings that make it unmanufacturable or difficult to manufacture (adding to the cost), so Harvan engineers will make suggestions for modifications to the drawing/part in order for it to work from a manufacturing aspect.
Suggestions to remove details that add costs without changing the part’s function can be a part of the first step of prototyping.
Stage 2: Manufacturing Quote
The engineers then prepare a quote. They go out to source the material and then find good pricing for the material and incorporate that into their quote. Of course, the time to manufacture the part is factored into the final quote on the product.
Harvan will develop a “Bill of Operations” which is a detailed listing of what steps that it takes to make a part. Harvan uses Activity-Based Costing – each activity will have a particular cost associated with it based on the expense of the equipment used and the skill of the employee using that equipment.
Stage 3: Manufacturing the Part
Once the order is received, the quoted method of manufacturing is again looked over by Harvan’s engineering staff to ensure that all the materials being used are the proper ones based on the TDP. In addition, the manufacturing process is also reviewed to again make certain it is correct before going to production. This is a second line of quality control put in place in order to make sure all the specs are adhered to before the work order goes forward into production.
After engineering has a look, the engineers will qualify any welding to the standards recommended by either the Canadian Welding Board (CWB) or the American Welding Society (AWS).
Stage 4: Quality Control Checks
First off Inspection – we run off one piece, and the machine operator will have someone other than the operator review to make certain it is correct. Afterward they do a 10% Inspection – so that every 10th part is inspected to make certain that the tolerance remains in place or if the machines need to be readjusted to meet the drawing. Finally, before the part is shipped to the customer, there is a Final Inspection to make certain the part meets the client’s full requirements.
Whatever your application or part may be, we want you to be assured that our engineering staff will piece together the perfect parts from beginning to end. We leave no step behind!
