Main Frame Body for Pharmaceutical Tablet Press Feed Frame

Product Specifications

Technical details and manufacturing context for Main Frame Body

Definition

The Main Frame Body is the foundational structural component of a Pharmaceutical Tablet Press Feed Frame. It provides rigid support and precise alignment for all internal mechanisms, including powder distribution systems, filling stations, and compression zones. This component ensures dimensional stability during high-speed tablet production while maintaining GMP-compliant containment of pharmaceutical powders. Constructed from Stainless Steel 316L, the Main Frame Body offers corrosion resistance and durability suitable for pharmaceutical environments. Key parameters include an overall dimension of 800×600×500 mm (customizable per machine model), a weight range of 150–200 kg, and a machining tolerance of ±0.05 mm (ISO 2768-m). The surface roughness is specified as Ra 1.6–3.2 μm (ISO 1302), and the operating temperature range is -10 to 60 °C. The maximum pressure rating is 1.6 MPa, and the sealing class is IP54 (IEC 60529). Surface treatment includes phosphating and painting to enhance corrosion resistance. Mounting hole diameters are 12–16 mm, which must match the machine base plate. Note that the material grade HT250 (GB/T 9439) is listed as a reference for cast iron with high strength and wear resistance, but the primary material on file is Stainless Steel 316L. All values are directory references and must be verified with the legal manufacturer for the specific model and application. The Main Frame Body is critical for maintaining alignment of internal components, ensuring consistent powder flow and tablet formation. It is designed to withstand operational loads and maintain geometric integrity under high-speed production conditions. For procurement, verify that the component meets the required standards and specifications for your specific tablet press model.

Working Principle

The Main Frame Body functions as a stationary structural platform that maintains geometric integrity under operational loads. It provides mounting surfaces and alignment guides for rotating feed frames, powder hoppers, and tablet ejection systems. By ensuring precise mechanical positioning, it enables consistent powder flow and tablet formation. The frame absorbs and distributes mechanical stresses, preventing deformation that could affect tablet quality. Its rigid construction and tight machining tolerances ensure that all internal components remain correctly aligned during operation, even at high speeds. The sealing class and surface treatment contribute to maintaining a clean and contained environment for pharmaceutical powders.
