Thermoform Tooling
Product Description
Since 1990, L. L. Brown, Inc. has specialized in the production of molds for the plastic thermoforming and vacuum forming industries. During this time, we have perfected a mix of experienced personnel, cutting-edge technology, and state-of-the-art production techniques, allowing us to produce high quality tooling at a reasonable cost. All tools are manufactured to your mounting requirements (i.e. cooling, air, mounting holes).
Design
The process of mold production begins with a design. This can either be done completely by L. L. Brown, Inc. or imported from customer files into our CAD system using a variety of different formats, including DXF, DWG, PRT, CADL, and IGES. From there, the geometry is manipulated and exported to our Computer-Aided Manufacturing software, where the mold program is written. This CAM system provides the ability to cut virtually any shape imaginable with both two and three dimensional surfaces, such as blended, 3-D swept, and NURBS.
Verification
L. L. Brown, Inc. utilizes cutting-edge software which can build a "solid" model that is able to be measured, rotated, and sectioned on-screen. This allows us to test the mold program at each stage of development before any material is cut. Not only does this allow us to construct a "virtual" mold which can be compared to the original idea, but it also is very helpful in the detection of "wild moves" which can occur with even the best programmer. This is one of the many tools we use to implement the highest level of quality control.
Manufacture
While manufacturing is the most important step in the mold production process, it is also the least time consuming due to our comprehensive preliminary work. Because L. L. Brown, Inc. is a full service manufacturing organization, we can draw from a variety of different machining capabilities including CNC milling (60" x 30"), CNC turning (10" dia.), and manual machining such as milling, turning, grinding, and plate sawing. This gives us the opportunity to be more versatile not only in the styles of molds we produce, but also in the ways in which we produce them. In addition, we retain an extensive inventory of aluminum plate, ranging in thickness from 1/4" to 2". If material outside this range is required, it can be custom ordered with a minimum lead time.
Special Requirements
Frequently, the mold is only part of the completed product. L. L. Brown, Inc. has extensive experience in the production of special tooling, including plug assists, water plates, and master tooling. To provide total service, we also maintain working relationships with third party vendors in areas such as powder coating and gun drilling.
Some Additional Points
L. L. Brown, Inc. acknowledges the two-tiered nature of our business. In other words, if you don't get the job, we don't get the job. We also understand that there are three selling points for you as a vendor.
Keeping these points in mind, we have found that two things make us stand out from the crowd in our field.
