Tablet Compression Tooling

Riddhi manufactures D, B, BB, tooling configurations used in today’s International Market. The American Standard known as the TSM Standard and the European Standard known as the EU or Euro norm Standard. We also manufacture Single Punch Tablet Tooling.

Multi-tip tooling is a uniquely designed assembly. We provide solutions in tablet tooling where more than one tablet can be formed at each station in the press. The number of tips being dependent on the punch type, size and shape of the tablet.

More than one tip is accommodated on a single punch thereby helps in increasing in productivity which leads to higher outcome, whereas with its excellent feature like strong tip & less maintenance which leads to reduction in production cost. Non Pharma & Special Shape Tooling. We manufacture Bolus or Veterinary Tablet or Ceramic tooling to support virtually any bolus tablet press machine on the market today.

Special Coating to the tooling helps in eliminating common issues like sticking and picking. Hard Chrome Plating.

We recommend using dust cups with the punches to provide a secondary barrier to the upper punch seals. This also prevents oil & other debris from contaminating granulation and ensures production runs smoothly and cut back on cleaning time.

Steel quality is determined by a number of factors, including its cleanliness, the homogeneity of microstructure, grain size, etc. With a better understanding of steel quality and steel types, and with the experience of 40 years RIDDHI can help you make an informed decision about the tooling you choose.

Selecting the steel type for your tablet compression tooling is very important and many different types of tool steels are utilized within the tabletting industry, each with unique and advantageous properties. Most commonly, tablet manufacturers want to know how different steel types relate to their specific product and the benefits associated with each option. However, if you were to ask a tableting expert what type of steel should be used, the answer remains the same, "It depends."

Choosing the appropriate steel for production directly correlates with the product's formulation. How does the tooling relate to the specific product being compressed? Does the formulation require high compression forces? Is it sticky? Is it abrasive or corrosive? Steel grade composition, hardness and heat treat processing directly impact tooling quality and ultimately, the success of tablet production. Understanding how and why these components affect the steel used for your tablet compression tooling can help you make a confident decision and an investment in quality.

Each grade of steel is determined by its nominal chemical composition (Table ablove). The elements that contribute to the composition give different properties to the steel.

For example, chrome steels such as S7 are beneficial for sticky products because the additional chrome content yields improved product release characteristics. While higher carbon (D2 & D3) steels yield better abrasive wear characteristics that are beneficial for products such as vitamins that are high in calcium, magnesium and zinc.

Hardness is an example of a mechanical property that measures a material's resistance to localised plastic deformation. Hardness is important because it correlates with other mechanical properties such as tensile strength, wear resistance, yield strength and compression strength.

Rockwell Hardness tests the hardness of a compound by indenting the material and determining the hardness value based on the depth of the penetration (degree of localised plastic deformation) and load. Higher Rockwell hardness tends to increase abrasion resistance but decrease impact toughness (i.e. it has lower force ratings) and lower Rockwell hardness tends to decrease abrasive wear resistance but increase impact toughness.

The hardness of the steel is determined by the heat-treating process, which is a critical step in the manufacture of tooling. Even the best quality of steel can be ruined by poor heat treatment and a marginal steel made decent by good heat treatment. Heat treating alters the mechanical properties of steel by transforming crystalline lattice structures and by modifying the arrangement and concentrations of the chemical phases within the steel. Body-centered cubic, face-centered cubic, and body-centered tetragonal are three examples of unit cells that are fundamental building blocks for the crystalline lattice structure and phases. These unit cells give rise to the carbon alloy phases of ferrite, austenite, and martensite. The concentration of each of these phases will depend on the current state of the tooling.

The hardening temperature sometimes referred to as high heat is dependent on steel type, and caution must be taken to ensure that the appropriate hardening temperature and holding time are implemented in order to prevent excessive grain growth. Excessive grain growth may lead to detrimental mechanical traits. Tempering is the final heat treatment process which can also facilitate phase transformation for certain steel types. More importantly, though, tempering will relieve the internal stresses created by the hardening process.
