The continuity of the crushing operation requires a certain order of operation between the start and stop of each equipment, otherwise it will cause the crusher to clog and interrupt production, and even cause serious equipment accidents. Therefore, in order to control the equipment between the crushing operations, a corresponding logic control system is designed. It can use logic control systems composed of logic devices such as relays, magnetic components, and semiconductors. However, due to the shortcomings of such logic devices, such as low anti-interference ability, poor stability, and easy damage, they are gradually replaced by more reliable controllers such as programmable controllers. The programmable controller overcomes the shortcomings of the above logic devices, and is flexible and convenient to operate and reliable in operation. For different applications, no major changes are required in the hardware, mainly to modify the programming software, which is very convenient to use. The sequence controller should meet the following requirements: (1) Each equipment must be started in sequence at a certain time interval in the order specified by the process. The starting sequence is opposite to the running direction of the mineral material. The crusher is usually started first. (2) Each device can be started separately or in groups. (3) When the production of the crushing is stopped, the order of stopping is opposite to the order of starting. (4) When a certain equipment in the crushing system is forced to stop, in order to avoid problems such as blockage, all other equipment supplying the equipment and mineral materials must also stop, but its subsequent equipment can not stop. (5) In order to improve the on-site environment, the dust removal equipment is first started, and when the system is parked, it is necessary to stop at the end. For example, the three-stage fracture shown in Figure 5-2-1 The automatic control of the mine-distributing trolley is to distribute the qualified products of the belt conveyor to the grinding powder ore bin to the various mine bins. In order to prevent the ore from being segregated in the mine, and to ensure uniformity of the ore-feeding grain size, it is usually controlled automatically according to the timing and order of the number of powder mines. This system is part of a sequential control system.

FAQ:
Q1: What tolerances can you achieve for Automotive Interior Plastic Injection Mould?
There is not a given set of tolerances that fits all processes and materials. In every case, the final tolerances on your part will depend on a number of factors, including but not limited to:
We will review your design and provide a design for manufacturing review, pointing out any areas where we may not be able to achieve your desired tolerances. It`s helpful to us if you can specify which areas in your design have critical tolerances that must be met and which can be slightly modified if needed to reduce time and costs involved.
Q2: How do you ensure your Automotive interior plastic mould quality?
In order to deliver high-quality parts every time, we`ve instituted the following steps to ensure you get parts that meet and exceed your expectations.
Q3: Is the lead time in working days or calendar days?
Lead times are quoted in working days. As per our terms and conditions, quoted lead times commence only after completion and confirmation of design for manufacturing review and the beginning of actual production.
Q4: How long does a quotation take?
In most cases, we respond within a couple of days of receiving an RFQ. However, there may be situations when we must source material from an external supply and therefore the quotation may be delayed accordingly.
Q5: What is the difference between a multi-cavity mold and a family mold?
A multi-cavity mold has multiple cavities of the same part; a family mold produces a set. For instance, for an electronic enclosure, you may need a front, back, battery door, and a button. Those could all be molded at once in a family mold.
Q6: How long does it take to build an Automotive air conditioner injection mold?
Depending on complexity and our tool room load, it can range from 2 to 12 weeks.
Q7: Can I modify the mold after the first run?
We can modify our steel molds by additional machining, fill-in welding, welding in additional material, or inserting a replacement feature, for a reasonable cost. If the changes are too great, however, producing a new mold may be more cost-effective than reworking the existing one.
