What are the safety protections of the Quick Mold Change System （Ⅰ）

When we talking about the Quick Mold Change System, everyone thinks of the advantages of time-saving, labor-saving, convenient..., etc. About the safety protection, we think that few people may notice this part. Now, let us instruction on the safety protections of the Quick Mold Change System.

First, let’s instruction on the hydraulic of safety protections:

● Each hydraulic circuit has the function of check and avoiding oil leaking：
When there is no air pressure or electricity and no oil leakage in the outer tubes. The system pressure can be keeps more than one week (Non-leak valve made by SANDSUN that can be hold the pressure more than 3 years)

● This system can add pressure automatically when the pressure reduction:
The hydraulic pump is driven by air. Once the hydraulic pressure reaches the pressure setting, it stops pumping which is energy saving. Meanwhile, if the working pressure reduces, the pump would supply pressure automatically to keep working pressure continuously.

● Each hydraulic circuit has the function of inspection pressure and can be interlocked with the machine:
Each hydraulic pressure has a pressure switch. When the pressure is lower than the setting of the pressure switch. The signal will be sent to the machine to stop the machine to prevent accidental occurrence.

● It adopts the intersecting direction to clamp the mold:
One of the circuit is abnormal of the hydraulic pressure, the diagonal die clamp will still clamped the mold, and then match the pressure switch, when the pressure is lower than the pressure switch setting. The signal will be sent to the machine to stop working.

● When the power is cut off, the die clamp will automatic clamping the mold:
This system adopts the design of automatic clamping the mold when the power is cut off. If the power cut off suddenly, the die clamp will is still clamping the mold and it does clamped the mold.

Installation of the quick mold change system on the 6500T largest injection machine in Australia

Hard case: Super large tonnage, all round modularization plastic injection machine
In order to meet the needs of the market and the demand of manufacturing automatic is increasing. We use our best to save time for the mold change and ensure the safety of the operation. Australia's largest and most respected dealers of machinery distributor had been cooperated with SANSUN several times. SANDSUN gets the chance to opportunity to participate this a major project with the Australia’s Company. In 2018, our customer purchased a Chen Hsong’s 6500T-the largest plastic injection machine. This 6500T plastic injection machine is using the advanced ultra-modular design to allow the user "mix-and-match" between the clamping and injection units according the needs. In order to meet the needs of the productions, our customer immediately thought that SANDSUN's quick mold change system can be perfect matched with the machine.

Past successful cooperation experience with quick mold change system wins the trust of customers
In the beginning, our customer questioned whether SANDSUN has the ability to complete this project. The main reason was they only used the quick mold change system for the max plastic injection machine only 2200T but this time is 6500T. However, our customer considered the experiences of using SANDSUN’s quick mold change system really improved machine productivity and product quality. Therefore, our customer trusts SANDSUN and decides to let SANDSUN to perform this project. During the process, SANDSUN always discussed and checked the details of the drawing carefully and constantly with our customer until the end.

As the mold change system not only saving mold change time but also improving production, reducing labors costs and work more safety. All of the goods would be over the cost of the investment.

Multiple safety mechanism design of Sandsun customized quick mold change system

It is an era for making high frequency mold change with multiple patterns and small quantity. In order to save time for the mold change and ensure the safety of the operation and save more production costs, it is just in time to apply Quick Mold Change System(QMCS).

Significantly improve the safety of Quick mold Change System(QMCS)
When customer using Quick Mold Change System, some customers worry about the hydraulic clamp will damage from the hydraulic tube, which will cause the hydraulic pressure to drop, and the clamp will not have enough pressure to clamp, causing the clamp to slip. The hydraulic pump unit has pressure switch in each circuit to detect it. When the pressure is lower than the safety pressure setting, the machine will be notified to stop immediately to ensure that the machine will not continue to produce, causing mold damage or operator injury.

Avoid mold damage and save production costs
In order to avoid customers’ doubts, SANDSUN also designed a safer hydraulic clamp-Check Valve Clamp. This clamp with build-in check valve, it can keep the pressure itself. Even if the hydraulic tube is damaged, the clamp will not release. There is no need to worry about the mold damage if there is a problem with the hydraulic tube during production.

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.

Sandsun's die clamping system realizes that adaptive quick die change fixture design closer to customers

In recent years, in response to customized products, a small number of diverse high-frequency mold-changing production types have made SANDSUN also work harder to meet customer needs.

More adaptable, CBL type quick die change fixture
Often when customers want to introduce and use Quick Mold Change System, in addition to the actual situation of the machine, it is also related to the part of the mold. Generally, when Quick Mold Change System is used, and the thickness of the mold base plate needs to be standardized (unified thickness), and the range is about +-2mm only. This will be an important part of customer concern. However, SANDSUN introduced CBL-type die clamping system to meet different customer needs.

Save more cost, no need to modify the mold bottom plate
CBL type die clamping system can be adapted to the requirements of 0~-10mm mold thickness plate. (For example, if the CBL type die clamp produced with H size 40mm, the mold base thickness range that can be used from 30~40mm. If the customer’s original mold base thickness isn’t have too much difference, customer can directly use the CBL type die clamp, that is, you can use the quick mold change system immediately without modifying any mold bottom plate.

Die clamping system closer to customer needs
SANDSUN has always provided customized products in response to the needs of customers, so that customers can more easily choose products that suit them, and thank customers for affirming SANDSUN's product quality and service.

Easier maintenance-Quick Disconnect Sensor

In this era of a small amount for diversified production, where can we create more production time?

In November 2019, we cooperated with customer “Goodman” in the United States to introduce a quick mold change system (QMCS). The customer used SANDSUN QDC to instead of the traditional manual screw to fix the molds.

Customer chosen the CA-N type (clamp with sensor) for their all production in this project. There have about 20 press machines have been installed, and it is expected to be fully used in 50 press machines in the customer's factory.

Our quick mold change system is currently in normal use, but at the same time, the customer still considers the issue of service and maintenance afterwards.

In response to customer needs, the problems caused by the mold colliding with the sensor are not avoided, and it takes a lot of time to replace the sensor and all the circuits and coupled with the limited maintenance personnel in the customer's factory. This problem may cause delay and occupy a lot of the production time, it is necessary to change the sensor to quick disconnect type together with the R & D so that the customer can save more time.

SANDSUN has always provided customized services and strives to meet customer needs. Not only in the improvement of our own products, but also to assist customer’s to consider the maintenance and sales services.

Customers also affirm that we help provide better choices, so that they can save more time later, thereby improving production efficiency.

How to complete the mold change easily and without a overhead crane?

It turns out that you can also use the mold cart and quick mold change system to change the mold when the factory does not have a overhead crane!

In June 2018, Moldex3D, a well-known mold flow analysis software company in Taiwan, purchased a mold change cart and quick mold change system from SANDSUN to solve the problem which is no overhead crane to change molds due to site factors. Due to use SANDSUN’s system, Not only It saves more time and improves production efficiency, but also improves the safety of personnel changing molds, comparing to traditional mold-changing methods.

Moldex3D is a well-known Taiwanese mold flow analysis software expert. When the injection machine was first purchased, the mold-changing method was not considered. When the machine arrived at the show room, it was realized that the mold could not be changed smoothly. Fortunately, it found SANDSUN, who can provide better and easier solution to its limitation of show room.

In this cooperation, Moldex3D engineer Tim also shared with us: In addition to solving the problem that we can't change the mold properly without a overhead crane, the “side-to-side” mold change method also makes it easier and faster for us to change the mold. It makes our job much easier and safer.

Because our staff is not a professional operator of plastic injection products and there is no professional mold change worker, we are very new to mold change operations. According to experience, general mold change operations take at least 30-60 minutes. Since we use SANDSUN’s mold change cart and quick mold change system, it only takes 10 minutes to complete the mold change, and the efficiency is increased by 50-80%. Even non-professional mold change people can easily complete the mold change work. With SANDSUN mold cart and quick mold change system, there is no need to worry about mold-changing problems in the future. In the future, new molds will also develop standard back plate to use the mold change carts and quick mold change system. To prepare for automatic mold change earlier.

This case successfully helped the customer to solve the problem of mold change and injection molding tool carts , and also made the customer affirm SANDSUN’s professionalism. SANDSUN always supports customers to solve problems and improve production efficiency, and assists customers to move towards the trend of Industry 4.0.
