About Die Cast Aluminum Platform Scale Frames
The die cast aluminum platform scale frames are cast aluminum components featuring a rectangular or X-shaped profile.
Mounting holes for leveling feet are provided at the four corners, which are reinforced to enhance load-bearing capacity; the central section incorporates a load cell mounting area, an overload limit boss, and a cable routing channel; the top surface of the scale frame is flat to support the scale platform.
The aluminum alloy material effectively reduces the frame's weight, thereby improving the scale's portability; the die-casting process integrates multiple complex features into a single component, reducing the variety and number of parts while enhancing the scale's overall structural integrity and minimizing the risk of failure.

Why Choose Die-Cast Aluminum for Platform Scale Frame
Compared to welded or cast-iron frames, die cast aluminum platform scale frames feature lightweight, smooth surfaces, and outstanding rust resistance.
These attributes enhance the scale's quality and durability, underscore its positioning as a mid-to-high-end product, and create a key selling point.
1. Portable
Lightweight aluminum alloy frames are 30–45% lighter than welded or cast-iron frames of the same design.
For platform scales requiring mobility for multi‑location weighing, cast‑aluminum frames enable easy handling and relocation.
2. Rustproof
Welded or cast-iron frames typically require a surface coating to prevent rust; however, if the coating is chipped or scratched during handling or use, the frames will quickly begin to rust.
In contrast, aluminum alloy frames are resistant to rust; even if the surface is damaged, the material rapidly oxidizes to form a new protective oxide layer that inhibits further corrosion. This ensures long-term durability in environments such as food processing plants, wet areas (like seafood or fresh produce stalls), and humid factory facilities.
3. Stable Weighing
Welded carbon steel frames are subject to welding stresses; long-term use often leads to deformation, resulting in significant corner errors that compromise weighing accuracy.
In contrast, die cast aluminum platform scale frames offer high inherent casting precision, delivers high dimensional accuracy for general profiles.
When combined with CNC precision machining for the load cell mounting bosses, these frames ensure consistent individual precision and batch uniformity even in mass production, providing a solid mechanical foundation to achieve OIML Class III accuracy after complete assembly and calibration.
4. Fast Zero‑Return
Cast aluminum frames offer superior vibration-damping capabilities compared to cast iron frames; they absorb vibrations more rapidly, allowing for faster display of final measurement results and quicker return to zero.

FAQ
Q: What is the salt‑spray resistance duration of scale frames with different surface treatments?
A: General anodizing: 96-300 hours;
Hard anodizing: 500-1000 hours;
Powder coating: 200-800 hours;
Electrophoresis: Over 800 hours.
Q: What is max platform size & capacity for die cast aluminum platform scale frames?
A: Normally 300×400 mm to 500×600 mm, 30‑300 kg. Larger size/capacity will cause excessive deflection and poor corner error, use welded steel frame instead.
Q: Can one die‑cast frame support multiple capacities?
A: Yes, by swapping load cells; however, you must not exceed the frame's designed maximum capacity.
Insufficient rigidity leads to bad corner‑error even with higher‑capacity sensors.
Q: What payment terms do you offer? Do you provide credit terms for long-term partners?
A: 30% deposit in advance, full balance paid before shipment. Clients with stable cooperation over 1 year and qualified annual purchase volume may apply for negotiable short credit terms.
Q: Which surface finish is recommended for food workshops and chemical corrosive environments?
A: Epoxy‑polyester powder coating is the recommended surface finish for die‑cast aluminum platform scale frames working in food workshops; Die‑cast aluminum frames are NOT suitable for chemical corrosive environments, you should select full stainless‑steel scale construction instead.
Q: Will weighing deviation or value drift occur?
A: Our high precision machining holds tolerance ≤0.05mm with consistently accurate mounting holes. The frame keeps undeformed under long-term full load, fundamentally avoiding unbalanced load and weighing value drift.
Q: Does die‑cast aluminum scale frame guarantee good corner error?
A: No. The four load‑cell bosses must be CNC milled to ensure flatness and height deviation.
Q: Which load‑cells are compatible? Can I use single‑point load‑cell?
A: Designed for four shear‑beam load‑cells. Not compatible with single‑point load‑cell due to different supporting structure.
