In the modern steel door manufacturing industry, the roll forming solution occupies a key position. The program mainly focuses on all kinds of steel door frame molding processing, has excellent applicability. Whether it is civil security doors, building fire doors, or medical and electronic industry used in the purification of the door, it is able to cope with the complexity of the product size, to fully meet the diversified production needs.

Compared with other production programs, roll single production program has significant advantages. Compared with the traditional bending single-machine production program, its degree of standardization is higher, the level of skills of workers less demanding, effectively avoiding the human factor caused by product obsolescence and rework. Compared with the rolled line production program, the rolled single machine process is relatively independent, will not be due to a single mold failure caused by the entire production line downtime. In addition, the initial investment costs are relatively low.

In terms of working principle, after the coil material is loaded, the equipment relies on the roll roll molds, using one by one molding process to extrude and shape the door frame cross-section. Each process is equipped with high-precision testing and control system, which can strictly control the precision error of the door frame section, thus strongly guaranteeing the product quality. At the same time, in order to meet the demand for different lengths, the machine is equipped with an encoder, which can accurately position the length. When the customized cutter receives the instruction to cut off the material, the splicing port can complete the molding synchronously, and the whole production process is smooth and efficient, which greatly reduces the defective rate and cuts the production cost. For the case that it is not possible to carry out chopping on the line, it is possible to realize the flexible combination of different splicing methods by configuring the chopping equipment separately. After the frame is molded, the corresponding holes can be stamped according to the matching requirements of the hardware doors, showing a wide range of applicability.

Door frame type is fixed, and the daily output demand ≥ 100;

splicing process and hardware door with a variety of the same frame type that is made of fire doors and security doors;

All equipment are customized equipment, mold curing, a mold a shape, such as the need to switch products need to replace the mold to recalibrate the mold cycle is long and high requirements for the skills of mold changers;

process beat is not uniform, there will be some equipment stagnation;

The most cost-effective, that is, there can be capacity to meet, the initial investment is not very high, the automation program is also okay, is the preferred option for most manufacturers;

standardized molds, the workers operating skills do not require high;

Recommended Requirements

Door frame molding machine

Equipment Overview

is used for door frame extrusion molding, after molding can be cut off according to the length requirements, cut off can be equipped with a straight cutter/circular saw 90 ° flat cut, followed by beveling, or can be equipped with a step knife in the cut off at the same time a one-time completion of the splicing of the beveling of the mouth molding (most of the structure can be achieved, the special structure may be required to the line of the second beveling), or a combination of multiple knives, according to the needs of the selection! It can also be combined with multiple knives and selected according to the needs, one machine can complete a variety of splices chopping, but can not carry out 45 ° chopping, it is necessary to separately configure the circular sawing machine or hydraulic punching and shearing machine to realize;
