Tablet press die ordering problems to pay attention to
In order to make the drug factory users can better order the appropriate die, this paper makes some simple introduction, and it is suggested that the drug factory users can first have a full discussion with the die manufacturer, in order to reduce the problems that may arise during production.
1. Due to some characteristics of track design and processing technology, it is suggested that users must choose products from the same factory for tablet press and die. Do not blindly pursue cheap and buy inferior die, resulting in the damage of the tablet press.
2. Choice of tablet type: Correct choice of tablet type is a successful step for the tablet press. For example, chewable tablets have high requirements for hardness and can be easily chewed. Most of them are inclined flat tablets. Shallow concave for thin film coating. Because there is no adhesive and lubricant in the raw material of traditional Chinese medicine tablets, it is required that the pressure of pressing tablets should be large, and the tablet type should be shallow concave. For tablets with large sugar content, shallow concave or flat tablet design is preferred. Alloy steel or hard alloy may be used for the middle die. Deep concave die die is easy to damage, as far as possible to use.
3. Consideration of the design of the die, film coating in the lettering depth and Angle of the difference; Corrosion caused by material acidity and alkalinity on punching die; The influence of traditional Chinese medicine or high fiber raw materials on the service life of the die; Whether the pattern and words will cause difficulties in sticking and punching in the process of tablet pressing; Effervescent tablets, vitamin C tablets, disinfection tablets, etc., have corrosive effect on the punching die, and the surface of the punching die should be treated with special film. For some acid, oxidized material die should use carbide material.
4. Consideration of the quantity of the die: in order to take into account the partial damage during use, as well as the waste in the manufacturing process, it is suggested that customers order 1.2 times of the actual production needs; For long-term users, it is suggested that the first batch of manufactured die should be kept as the retention sample of 12 new products, and the retention sample should always be taken as the standard when replenishing the die.
