A mold is a special injection molding tool. Custom molded component manufacturers design and fabricate the mold specifically for the part they'll produce. When the production run for a part is finished, specialists replace the mold with a new mold for the next part they need to manufacture. Several types of molds exist for injection molding.
The mold determines the part's shape and size. It's also the special tooling in injection molding. When making large, complex parts, a mold may cost hundreds of thousands of dollars. When it comes to smaller parts, manufacturers can create molds with multiple cavities, adding to its cost. Incidentally, injection molding is most economical for large production quantities.

Armored thermocouple installation
Armored thermocouples offer many advantages such as bendability, high pressure resistance, fast thermal response time, and durability. Like industrial assembled thermocouples, they are used as temperature-measuring sensors and are usually associated with display meters, recording meters, and electronic regulators. It can also be used as a thermoelement of a fabricated thermocouple. It can directly measure the temperature of liquids, steam, and its gas medium and solid surface from 0°C to 800°C in various production processes. Compared with fabricated thermocouples, armored thermocouples have the advantages of flexibility, high pressure resistance, short thermal response time, and durability.
Armored thermocouple installation instructions
1. The mounting height of the briquetting must be the same, usually 150~200mm above the level;
2. The welding of the briquette requires three sides for spot welding, and the thermocouple insertion mouth should not be spot welded. The side spot welding should pay attention to not stopping the stop screw to weld.
3, the pipe wall temperature should be installed symmetrically up and down;
4, armored thermocouple must be inserted in place, stop the screw tightly in place;
5, armored thermocouple leads to the proposed use of small box;
6, armored thermocouple fixed stainless steel wire must be used to replace;
7, armored thermocouple and furnace wall interface must be bandaged, and then threaded into the homemade protective tube leads;
8, in order to prevent the settlement of the boiler, it is recommended to use the transition junction box, and then use the compensation lead to connect to the front device;
9. The bridge or protection tube of the furnace wall and the front-end device should not be closed type. It is necessary to prevent the high heat flow from directly entering the front device and damaging the components inside. (Tianjin Power Construction did not pay attention to it, resulting in the front device. damage);
10, the position of the front device can not be too far, otherwise the length of the thermocouple is not enough;
11. The wiring should be correct and reliable.
Armored Thermocouple Tips
1. With a flexible performance, armored thermal resistance can be used to make any direction of bending in addition to the head, so it is suitable for the construction of more complex, Di small equipment temperature.
2. Armored thermocouples have good vibration and impact resistance. Therefore, the life of the thermal resistor is longer than that of the conventional thermal resistor. The following issues must be observed when using the thermal resistance.
3. The use of armored thermocouples has a long service life. Since the resistor body of the Kay mounted thermal resistor is protected by the twisted cover of the iron-incorporated data and the maintenance of the metal sleeve, the thermal resistance wire is not easily eroded by harmful media.
4. The explosion-proof thermal resistance is limited to the junction box by the special structure of the junction box, and the explosion of the explosive mixture of the inside of the shell due to sparks or arcs.
5. The production site will not lead to an explosion. Flameproof RTDs can be used for temperature measurement in explosion-hazardous areas in the Bla-B3c class. Anti-corrosion thermal resistance 5) Anti-corrosion thermal resistance uses PTFE anti-corrosion material.
6. As an integral protective sleeve or two-piece sleeves, it is also possible to directly perform anti-corrosion treatment of the material on the protective tube, divided into three forms of spraying, sintering and sleeve sealing.
7. Suitable for measurement in corrosive media of strong alkalis, with a temperature resistance of 250°C. Fixed installations can also use the same thread with PTFE.
8. Based on the measurement temperature range and side volume objects, select the appropriate type, specification, and maintenance tube information for the thermal resistance.
