Project Title Injection Molding for Corrosion Tests Modernization

General Information

1.0 Background and Purpose

The US Forest Service (USFS), National Technology & Development Program (NTDP), Wildland Fire Chemical System (WFCS) Laboratory is in the process of completing a revision update of the specifications for Qualified Product List (QPL).

These specifications include a variety of tests and evaluation of the different product’s physical characteristics. Corrosion testing is part of each of the specifications, and within this testing category there are three different tests conducted.

Testing is done for uniform, galvanic and crevice corrosion using metal alloy and low-density polyethylene (LDPE) test specimen coupons. The setup for these tests is similar and goal and deliverable parts from this acquisition will modernize that setup and increase efficiency saving staff time and improving the overall test setup and process. The testing involves the assembly and test specimens being suspended in a standard 32 OZ straight sided glass jar, (figure 1) and a lid is screwed onto the top prior to the jar and assembly being place in either a 70-or 120-degree Fahrenheit incubator for an exposure duration of 28 to 90 days depending on the test.

The parts designed for this modernization of the setup and test process were created using a 3D printer for proof of concept. These four separate parts are to have injection molds fabricated and tooled so that a large number of individual parts can be manufactured from injection molding using PEEK resin. The four separate parts are, a Threaded Rim-Ring Top , (figure 2), a Dipping Shaft – Pincher, (figure 3), a Dipping Shaft – Galvanic, (figure 4) and a Dipping Shaft – Crevice, (figure 5). Figures 2 – 5 are 3D printed examples of the parts to be produced, proprietary PDF’s and CAD drawing files will be available to vendors upon request. These drawing files are the intellectual property of the USDA Forest Service, Wildland Fire Chemical Systems at the National Technology and Development Program in Missoula Montana. Requests for the proprietary PDF’s and CAD drawing files shall be sent to michael.simpson@usda.gov. These parts will be created using injection molding of PEEK resin so all the Threaded Rim-Rings can be used interchangeably with any of the Threaded Dipping Shafts depending on the test being performed. These parts will be able to withstand being cleaned in a domestic dish washer for reuse and be durable for conducting numerous test cycles.

The Wildland Fire Chemical Systems Program would eventually like to have 6,000 to 7,500 of the interchangeable dripper top (Rim Rings) and 2,000 to 2,500 of each type of dipper shafts for each product we test. (These will be used for each product we test retardant, foam, gels).

The base year/initial batch of 1,000 interchangeable dripper top (Rim Rings) and 500 of each type of dipper shafts would be used for testing and to develop a cleaning process for them and to reuse them as many times as possible in the first year to determine the durability of the injection mold parts. If no further modification is required, we would purchase a mix of the parts to acquire the number of each to have the desired additional individual part numbers to support the testing of each product.

Agreement Statement of Work

3.0 Technical Requirements / Tasks

3.1 For Injection Mold Fabrication and Tooling and Part Production

• Collaborate and consult on the design, development, fabrication and tooling of the parts molds.

• Maximize the number of individual parts that can be produced per mold injection cycle to batch individual parts.

• Provide a pricing schedule for the manufacturing of the parts. (For example, if there are minimum quantities or bulk pricing discounts depending upon the quantity of parts ordered). The government reserves the right to order quantities based on the vendor's provided pricing schedule. The government is not obligated to purchase a minimum number of parts in any ordering period/option year.

• To provide subject matter expert technical input and assistance regarding the best practices and mold creation to provide the most durable mold and deliverable parts from the injection molding process.

• To provide subject matter expert technical input and assistance regarding recommendations, for the number of parts possible per mold or family mold.

• To provide a “first batch set of 20 of each part for initial lab use testing to determine proper dimensions, functionality, durability and ease of cleaning for reuse prior to large batching of individual parts.

• To share the mold specification designs and renderings and retain the molds for future batching of all four parts.

4.0 Deliverable / Schedule

The schedule and deliverables are driven by the timing of contract award and the initial coordination on the initial mold fabrication and tooling estimated to be 6 weeks from initiation of contract award. Approval of all molds and refinement of design features and initial injection molding of parts will be coordinated and provided by the contractors estimated delivery schedule.

5.0 Work Location

The work within this agreement will be performed at the vendors’ facilities.

6.0 Travel

No travel will be required virtual coordination meetings can be arranged with the vendor, if the vendor awarded the contract is within the local commuting area of the National Technology and Development Program (NTDP) center in Missoula Montana the staff from the Wildland Fire Chemical Systems (WFCS) laboratory can make arrangement to meet with the vendor in person at their facility.

11.0 Performance Requirement Measures

Quality assurance will be performed by the Government during the agreement period of performance at regular intervals.

Methods may include visual survey and/or agency comments. Incomplete or unsatisfactory work may include rework to achieve the acceptable outputs and/or deliverable.
