How to choose Quick Die Change System FAQ
1. Many customers call to ask if they use other brands of Quick Die Change System and would like to replace it with SANDSUN's QDCS. Is it applicable?Of course, but you must provide more information about the old Quick Die Change System first. SANDSUN has a professional QDCS team that can plan and select appropriate replacements for customers.
2. How to choice the Die Clamp?
①Total clamping force which the machine needs (Σ F)
=Machine capacity (Tons)×15%~20%
Upper clamp (Σ F1)=(Σ F)×60%
Lower clamp (Σ F2)=(Σ F)×40%
Upper clamp ( F)=(Σ F1)/ n (tons)
Lower clamp ( F)=(Σ F2)/ n (tons)
200T×15％=30 (Total clamping force which the machine needs)
30×40％=12 (total clamping force of lower clamp)
18 / 4=4.5 (Each upper die clamping force have to over than 4.5 tons)
12/ 4=3 (Each lower die clamping force have to over than 3 tons)
3. What is the difference between CA model clamp and CB model clamp?
CA model clamp is suitable for the template with the U slot.
CB model clamp is suitable for the template without the U slot.
4. How should I choose PB or PC model Hydraulic Pump Unit?
The total quantity of die clamp does not over than 12 PCS, the PB series can be selected. When die clamp used more than 16PCS or over 16 tons, the PC series Hydraulic Pump Unit is recommended. Because the flow rate of the PC pump is larger than PB pump, and hydraulic pressure filling speed is faster as well.
5. How to choose "Die Lifter"?
According to the weight of dies the size of the plate and the operational request. SANDSUN has hydraulic die lifter DL model (Roller type)、DB model (Ball type) or spring model of DL and DLS Die lifter.
6. When the platen with the hole, which model of die lifter should be used?
We have two stepped die liter and removable die lifter can be selected.
7. There are only T-slot on the platen, can the die lifter be shared with T-slot?
Yes。However, it only can be used removable die lifter, and have to pay attention to whether the T-slot’s width (W) is same as the die lifter’s width (W)
8. If the U-slot depth (H) of die lifter is deeper than the standard specifications in the SANDSUN ‘s catalogue, can it be used?
Yes。But cannot be less than standard specified in the catalogue.
9. How to choose "Die Arm"?
According to the size and weight of the die that select the applicable length and maximum capacity of the Die Arm.
10. If use RD model (Hanging type), what should we pay attention for?
The hanging length of RD model should be less than the height between the platen and the ground, otherwise the arm cannot be completely hanging down and closer the machine body.
11. If use RE/RF model (Folding type), what should we pay attention for?
RE/RF can be folding outward or inward for storage. If the RE/RF to be folding inward, the distance for installing the two arms should be more than the distance between the installations.
12. The weight of the die is heavier than 3 tons, is there a suitable die arm for use?
You could choose RS model (Heavy duty). Single RS model die arm can support around 3 tons of the die weight. If you have special requirements, you can provide more information let SANDSUN for evaluation.
Benefits of Quick Mold/Die Change System
In the recent years, the way of product’s demand has changed from traditional mass production into multiple and small quantity production. Many factory owners have to face the big environmental stress, such as delivery date shortened, production cost reduced, the quality of product improved, and so on. Hence, they try to find ways to solve and adapt the flexible production pattern. In order to greeting the era for making high frequency & mold / die change system with multiple patterns and small quantity, it is just in time to apply the Quick mold change system and Quick die change system with saving time for the mold / die change and ensuring the operation safety.
The best boost mechanism for injection and press machine
Quick mold change system and Quick die change system direct benefit is shorten time of die/ mold change、decrease time of production idle、increase capability of machine、adapt multiple and small quantity production and lower down the percentage of inventory; Also can be die/ mold and operation standardized、automation、achieve prompt production and sales、improve operation safety、company image and environment of factory. Let more young people have invest in this industry.
Therefore, It would be too slow If you haven’t use quick mold / die change system.
Suitable for small machines-DLS Die Lifter- Spring Model
The die lifter usually used with quick die change system on press machine and hydraulic press machine. The design of the die lifter is to use oil pressure to lift the die away from the lower platen, In addition to easy to use, it can also avoid the lower platen and the bottom of the die to worn out during the die sending process. But customer often do not want to use pump or controller due to machine space. If so, should we have other die lifter model to choose? Of course, you can choose to use spring type of die lifter.
If machine’s U-slot and T-slot is smaller, and the die is lighter. Customer can choose DLS spring type die lifter. The length of the die lifter is 200㎜& 300㎜ and the height range of slot is larger. It will be more matched with the size of the machine and U-slot.
In addition to the standard model of DLS die lifter. SANDSUN will according to different needs of customer, such as the depth of the lower plate, the weight of the die and the direction of die change etc…SANDSUN also can help customer customized the die lifter model.
We have a European customer, when their die moved into the machine, because of the structure of the machine, the die need to be moved in the machine after it is moved. Therefore, the customer requires use spring model die lifter with balls, so SANDSUN designed new die lifter-DBS model. For customer, DBS die lifter make it easier and more convenient to move molds in the machine.
SANDSUN has always provided customized products in response to the needs of customers so that they can use products that are more suitable for them. Also thanks customers for affirming SANDSUN’s product quality and services.
The Styrofoam machine also can use the Quick Die Change System
Quick Mold/Die Change System usually used in press machine, injection machine, die casting machine and blow molding machine. In the end of 2019, because of the GXXXD HX plastics company which they has another company to produce Styrofoam products ,also requires Sunny Friend Machinery to cooperate with SANDSUN. Customer request the vacuum forming machine have to install quick mold change system. This Styrofoam machine is the first time installed by SANDSUN.
Actually, The Styrofoam machine production method is not different of the injection machine. Both require the mold to be locked on the platen then the material is cooled to form. However, the mold is much larger than the general injection machine of the same tonnage, so it takes a longer time to lock the screw. Because the finished product is directly dropped when the mold is opened, the machine is usually erected at a certain height, and the bottom of the platen is suspended. Whenever a person changes the mold, the danger is higher because there is no foothold. The force of the locking screw is different and it is easy to fall down because the mold is not locked properly and the personnel are also prone to fall during the process. Nowadays, there is high frequency mold change with multiple patterns and small quantity. The customer strongly asked the two of us to use it.
Thanks for GXXXD HX company for their trust in SANDSUN products and development and service. Also grateful for the cooperation of Sunny Friend Machinery that completed this case happily and perfectly.
