    Main features of equipment Rotary Tablet Press GP-15

    The frame of the body is made of cast iron, and the machine runs more smoothly

    Combined upper guide rail design, easy to disassemble, maintenance, replacement, use double-sided lifting guide rail, punch force uniform, long life

    The centralized lubrication system (dry oil lubrication system, thin oil lubrication system and circulating lubrication system) provides enough lubricant to each lubrication part through automatic control to ensure the safe operation of the machine

    Large plate hole processing technology

    The processing technology of punching die holes of other manufacturers is normally cut by boring machine, because this processing method leads to the poor finish of the middle plate hole, and the later stage and the middle die can only be interference fit, resulting in the difficulty of entering and exiting the hole of the middle die.

    Grand's middle die holes in the boring machine cutting, and then each hole grinding processing, at the same time with the coordinate detection equipment for hole detection, to ensure the finish and accuracy of the hole. The processing cost is much higher. The punch plate is the most core workpiece of the tablet press, and its accuracy can fully represent the overall accuracy of the high-speed tablet press.

    For example, the coaxiality of the upper, middle and lower punching directly affects the quality of the sheet and the life of the die; The runout of the end face of the middle punching plate directly affects the powder leakage and yield.

    Change the mold directly by hand

    Grand's tablet press, without borrowing any tools, complete the disassembly of the mold by hand. The design and development ensure that the medium die hole of the plate of the high speed tablet press will not be deformed for a long time.

    Other manufacturers because of borrowing tools to knock on the mold to complete the assembly and disassembly, but borrowing tools to knock on the mold is easy to extrude metal chips, and labor intensity, low production efficiency, waste a lot of time, while years of knocking on the mold, so that the hole becomes elliptical, precision loss, up and down punch with the mold precision problems.

    Grand's freehand punching function can save at least 2 hours each time the mold is replaced, the mold is replaced once a week, calculated according to 50 weeks a year, then a year can save 100 hours in the mold replacement, such as the saved time is used for production, and the output of 150,000 pieces per hour can be increased by 15 million pieces, estimated according to Gliclazide sustained release tablets. It can increase sales by more than 10 million yuan per year, which is excellent value for money.

    Frequently Asked Questions (FAQs)

    Fully automatic high-speed tablet press GP-15

    1I have a tight production schedule. How long does it take to change the die (punch)?
    This is one of the GP-15's greatest advantages. Our tablet press allows for manual die changes, requiring no tools. Unlike tablet presses from other manufacturers that require hammering, die changes can take hours, but the GP-15's design minimizes this time. Each die change saves you at least two hours. If you change your die weekly, you can save over 100 hours of valuable production time per year.
    2Our Quality Assurance (QA) department has strict regulations regarding "black specks" or oil-contaminated tablets. How does GP-15 prevent lubricant contamination of tablets?
    We completely understand. The GP-15 is equipped with our uniquely designed oil collecting ring. It ensures the punch is fully lubricated while efficiently collecting any excess oil, preventing it from leaking into the tableting chamber. This fundamentally eliminates tablets with "black or colored spots" caused by oil contamination, ensuring your product quality meets GMP standards and reducing waste from tablet sorting and rework.
    3I've had a "crash" accident with a tablet press I've used before—the punch pulled the die out and damaged the feeder. How does the GP-15 prevent this costly accident?
    This is a key safety feature. The tapered push screws (point contact) used by other manufacturers pose a risk of the die being pulled out during sticking. The GP-15 utilizes a die push screw structure (convex and concave contact). This design provides "surface contact," locking the die horizontally within the ring groove, ensuring that the die will never be pulled out, even under prolonged, high-load operation. This maximizes safety, preventing long downtime and costly spare parts losses caused by collisions.
    4If I change the die without using tools (barehand), will the die hole become loose or deformed after long-term use?

Show more 938 / 5,000 No, this is precisely our core technology. Other manufacturers require tools to tap, which over time can cause the die hole to deform (become oval) and lose precision. Our GP-15 allows for manual punch changes thanks to the extremely precise large-plate hole machining technology. After cutting, our die holes are finely ground and subjected to three-dimensional coordinate measurement, resulting in extremely high smoothness and precision. This ensures a perfect fit in the die and prevents deformation even after years of use.
    5High precision is great, but how does it translate into actual benefits?
    High precision directly translates into benefits. Take our precision rotary table (large-plate hole technology) as an example:Higher yield: Extremely high punch concentricity ensures consistent tablet quality and reduces waste.Less powder leakage: Minimal runout on the punch plate end face directly reduces powder leakage and improves yield. Longer die life: Perfect concentricity reduces abnormal punch wear, extending the life of your expensive die.
    6Is the GP-15 complex to maintain and operate?
    Quite the contrary. The GP-15 is designed to simplify maintenance and improve efficiency. For example, the manual punch change feature (Advantage 2) is not only fast but also significantly reduces operator workload. Furthermore, the anti-collision design of the die screw (Advantage 3) and the oil-repellent oil ring (Advantage 4) mean fewer unplanned stops and less cleaning, allowing your team to focus on production.
    7Your tablet presses appear to cost more than standard machines. Why should I pay more?
    Our tablet presses are an excellent value for money investment. Take our die screw design (Advantage 3) as an example. While this system adds approximately ¥5,000 to the manufacturing cost, it avoids the cost of spare parts (such as forced feeders) that can cost at least ¥10,000 per year, as well as several days of lost production. Our manual punch change feature (Advantage 2) can save you 100 hours of work per year, which translates to an increase in production of tens of millions of tablets, resulting in significant sales growth. Your additional investment in the GP-15 will be fully recouped within a few months through increased efficiency, reduced waste, and avoided accidents.
    8Your turntable's precision sounds very advanced. What's the main difference between it and other manufacturers?
    The difference lies in the machining process. The turntable is the "heart" of the tablet press. Other manufacturers typically use only boring machines, which results in poor hole finish and forces the mold to be "interference fit" (forced into place), making mold changes difficult. Our process follows the boring machine with fine grinding and inspects each hole using a CMM.
