Topic: Development of drawings (design documentation) for two frames made of 1 mm stainless steel for thermal boxes (insectariums)
Hello!
I need to develop detailed design drawings (layouts for laser cutting, bending, assembly) for the production of two types of sheet metal frames. The boxes are intended for insect breeding, will be insulated with PIR panels, and equipped with a heating and ventilation system.
The assembly principle is completely non-welded, exclusively using bolted connections ("NO-WELD BOLTED CONSTRUCTION"), an example of the profile assembly logic is attached in the file 1000031697.png. The structure must be assembled manually and have high rigidity.
TECHNICAL REQUIREMENTS FOR THE PRODUCTS:
• Frame material: Stainless steel, sheet thickness — 1 mm.
• Wall filling (important!): Inside the frame profiles, thermal insulation PIR panels (PIR) with a thickness of 30 mm will be inserted. The panels have a standard size of 1200 x 600 mm. The frame and profile layout must be designed strictly according to this standard panel size to minimize trimming, ensure a tight fit, and eliminate thermal bridges.
• Assembly: Strictly with bolts, without the use of welding and rivets. The structure must reliably maintain rigidity and geometric shape after assembly.
• Fastening requirements: All fasteners (bolts, nuts, washers) must be designed to be strictly made of stainless steel (A2/A4) to prevent corrosion.
VENTILATION SYSTEM REQUIREMENTS:
In each of the two boxes, a ventilation system must be structurally incorporated with the following basic parameters:
1. Lower intake (with adjustable option):
◦ From the bottom left: an intake opening with a cross-sectional area of 150 cm², equipped with mechanical adjustment (damper) to change the airflow.
◦ From the bottom right: an intake opening with a cross-sectional area of 150 cm², also with adjustment (damper).
2. Upper exhaust (with adjustable option and cooler installation):
◦ In the center (at the top / in the lid): one exhaust opening with a cross-sectional area of 300 cm², necessarily equipped with an adjustable damper.
◦ Mounting place for cooler: This exhaust opening must be designed with a square mounting place for a standard moisture-proof axial fan (cooler) in a square housing with 4 fastening holes at the corners. The central working hole for the fan should be designed with a diameter of about 100+ mm. The exact installation dimensions of the cooler will be provided to the contractor at the start of work.
IMPORTANT ADDITION FOR PRODUCT NO. 2 (Horizontal box):
All ventilation openings (both lower intakes and the upper exhaust under the cooler) in Product No. 2 must be protected with stainless steel mesh. Mesh parameters: cell size — 0.8 mm, wire thickness — 0.5 mm. The designer must provide removable clamping frames with bolts for tight fixation and sealing of the edges of this mesh to eliminate gaps.

4. PRODUCT NO. 1: Vertical box
• Overall dimensions: Height — 2000 mm, Width — 1200 mm, Depth — 600 mm.
• Door and viewing window design: A door with a width of 600 mm must be located exactly in the center of the facade. The door must include a viewing window made of soft (liquid) glass. The window should be double-layered (on both sides of the door) — an outer and inner film contour with an air gap between them, to eliminate thermal bridges and avoid condensation. Provide clamping frames for fixing the glass on both sides.
• Door locking: A simple mechanical bolt based on the "finger in the hole" principle (pin bolt). Provide grooves in the frame and door for it.
• Ventilation: According to general requirements (without stainless mesh 0.8 mm).
1. PRODUCT NO. 2: Horizontal box
• Overall dimensions: Width — 1200 mm, Height — 600 mm, Depth — 600 mm.
• Cover design: Fully opening top cover (on hinges/bolts).
• Ventilation: According to general requirements + mandatory installation of protective stainless mesh (cell 0.8 mm, wire 0.5 mm) on clamping strips on all three openings.
1. WHAT IS REQUIRED TO BE DELIVERED:
2. 3D models of both boxes (in STEP / SolidWorks format).
3. Drawings of parts and assembly units (indicating the scheme of bolted connections and fastening nodes for meshes/glass).
4. Layouts of all elements in DXF format for laser cutting, taking into account bending coefficients for 1 mm stainless steel.
5. A specification table for the required stainless fasteners (sizes and quantities of bolts, nuts, washers).
6. I look forward to your proposals regarding the deadlines and cost of work for both products. Thank you!
