1.What Is Punch Friction In Tablet Pressing Process?

Punch Friction-Sourced:ducsonco

Friction happens in the pressing of your tablets. And in tablet pressing process, punch friction is the most common one which happens with the pressing work of upper punch and lower punch. Punch friction happens in the wear and tear of punch and die wall. Punch friction helps the forming of your tablets but it may also lead the wearing of your material parts.

The different punch friction makes different effect for your tablet pressing work. You may find the balance of it to make the suitable tablet pressing work here. And, you may also reduce punch friction for the higher efficient tablet pressing work.

2.What Are The Types Of Punch Friction In Tablet Pressing Machines?

What are the types of punch friction in tablet pressing machines? Here are the typical punch friction in tablet pressing machines.

Static Friction And Dynamic Friction-Sourced:diffzy

Static friction

Static friction is the friction which happened with no operating of high speed tablet pressing machine. Without any operation, there may be the friction which forbidden the work of punch. And static friction is the friction which forbidden the initial operating.

Dynamic friction

Dynamic friction refers to the friction punch make in the consistent tablet pressing work. Dynamic friction is the main friction road. And in tablet pressing work, there are sliding friction, rolling friction and so on which are all the type of dynamic friction.

3.What Are The Factors Which Affect Punch Friction In Tablet Pressing?

There may exist different punch friction in tablet pressing work. Have you ever wondered the factor which affect punch friction in tablet pressing?

Powder characteristics

Powder Characteristics-Sourced:atslab

Different powder makes different punch friction. You should consider the particle size, flow, cohesiveness and such factors for the affection on punch friction. The powder with poor flow and high stick can improve the friction and make more wear on punch and die parts.

Die and punch design

Die And Punch Design-Sourced:lfatabletpresses

The design of your die and punch should also be considered seriously for your punch friction. The smooth and sleek punch and die mold can help reduce the friction apparently. And the abrasive and rough die and punch can not make the low punch friction work.

Lubrication

You should also apply lubricants for the reduce of friction. The changing of formulation for better lubrication and applying of lubricants on machine parts can help reduce punch friction and maintain the best friction levels for your tablet pressing machine.

Machine settings

You may make the different machine setting and tablet pressing speed, compression force and tablet thickness can all affect the punch friction. The higher speed and compression force can lead larger friction and affect your tablet products quality.

Punch material

Punch Material-Sourced:osdmachinery

How about the material of your punch? There are stainless steel, carbide, coated alloys and so on for you to choose. Different material makes different job for your tablet pressing work and the friction level is also different. The punch with titanum or chrome coating makes the outstanding job in reducing friction.

4.How To Reduce The Punch Friction of High Speed Tablet Pressing Machine?

How to reduce the punch friction of high speed tablet pressing machine? Here are the comprehensive solution for you.

Adjusting the fit gap between the punch and die

Adjusting The Fit Gap Between The Punch And Die-Sourced:artizono

Check the fit accuracy

The fit gap between the punch and the die should meet the equipment’s requirements. If the gap is too small, it may increase friction, potentially causing the punch and die to seize. Professional measuring tools, such as feeler gauges, can be used to check if the gap is within the specified range. Generally, an appropriate gap is between 0.05 and 0.1 mm, with the specific value depending on the tablet press model and die specifications.

Mold design modification

Try to minimize the contact area between the press wheel and the die to allow the press wheel to pass quickly over the stress surface of the upper die, thereby increasing the equipment’s speed.

Repair or replace worn parts

After long-term use, the punch and die may become worn, causing the fit gap to increase or become uneven, leading to unstable friction. If wear is observed, timely repair or replacement of the punch and die should be carried out to ensure fit accuracy.

Optimize the lubrication system

Optimize The Lubrication System-Sourced:pharmacy-machines

Choose the right lubricant

Based on the tablet press’s working environment and requirements, choose a lubricant with good lubrication and wear resistance properties. For example, for high-speed tablet presses, a lubricant with low viscosity and good fluidity is preferable.

Adjust lubrication frequency and oil quantity

Increasing the frequency of lubrication and appropriately increasing the oil quantity can effectively reduce friction. However, excessive lubrication may contaminate the tablets or cause oil residue to accumulate on the punch surface, affecting tablet quality. Typically, based on the press machine's running speed and load, the lubrication cycle can be adjusted from once per hour to once every half hour, with each oil injection covering the punch surface with a thin, uniform film of oil.

Control the properties of the tablet material

Control The Properties Of The Tablet Material-Sourced:hosokawa-alpine

Adjust material moisture

If the material moisture is too high, its stickiness will increase, resulting in more friction with the punch. Drying methods can be used to reduce material moisture, usually controlling the moisture content between 3% and 8%, with specific values varying depending on the type of material. For traditional chinese medicine extract tablets, the moisture content is usually controlled between 5% and 8%, while for chemical drug tablets, it is controlled between 3% and 6%.

Improve material particle size distribution

Uneven material particle size distribution may cause poor material flow during the tablet compression process, leading to localized high pressure and increased punch friction. Sieving or other pre-treatment methods can be used to ensure a more uniform particle size distribution. Generally, the material's particle size distribution should range from 80 to 200 mesh, with particles in the 100 to 160 mesh range accounting for at least 70%.

Adjust the tablet press’s operating parameters

Reduce compression pressure

While ensuring tablet quality, appropriately lowering the compression pressure can reduce the friction between the punch and the material. The compression pressure can be gradually reduced, with each reduction of 3-5 kn, while monitoring tablet quality indicators such as hardness and friability, until the optimal pressure is found.

Optimize speed change gradient

When performing speed challenges, avoid sudden increases in tablet press speed. A gradual increase should be adopted, allowing the equipment and material to adapt. Observe changes in upper punch friction, and once friction stabilizes, continue to increase the speed.

When adjusting these parameters, closely monitor the operation of the tablet press and the quality indicators of the tablets to ensure that, while alleviating friction issues, the process validation results and product quality are not negatively affected.
