Furniture Edge Technology

Furniture Edge Technology

Veneer, edge banding, drilling is the basic furniture processing procedures, and the performance of edge quality is the most obvious.
In general, the edge furniture pieces to be machined according to the edge of the shape of the features can be divided into straight edge and curved edge. With the growing furniture promotion, direct edge in production, while maintaining the need to add some curve components, to beautify the product modeling to improve the value of the entire workpiece. Edge processing is slow, but the curve in the shape of the United States and also to increase the production speed limit.
Currently, most of the furniture's Edge on the Edge machine. Edge banding machine according to the degree of automation can be divided into manual, semi-automatic and fully automatic, you can use ordinary straight edge straight edge banding machine, you can also use a soft molded edge banding machine, edge banding machine after molding, dual-side sealing machines. Relatively speaking, the curve edge processing is more complex, you can use manual edge banding machines, machining centers, CNC Edge semi-automatic or fully automatic machine for.
Edge machine to be the choice of configuration depends on the shape of workpiece characteristics, the type of sealing material, but also consider issues such as productivity and quality.
Edge lines commonly used in office furniture and cabinets on the shape of a simple product, configuration, the main consideration of changes in production and features, such as PVC or ABS edge banding edge banding and other materials to be added scraper; of solid wood edge section, an additional finishing knife and sanding device; to ensure the quality of edge effects from low winter temperatures, the best choice for far-infrared preheating device with edge banding machines; other alternative is also a lot of additional configuration, such as automatic Tracking fillet trimming function, milling devices.
Edge curve can be processed in several ways. Most manufacturers use hand edge machining curved parts, especially those within the arc of the plate parts, sealing machine by wheel diameter can be processed to determine the maximum depth of the curve. Use hand-sealed curved edge banding machine is simple, low investment characteristics. However, due to the use of hand-Edge, the quality is relatively low, mainly in the bonding strength is low, repeat accuracy, rework rate is higher. Manual sealing machine for the same time the thick edge of the commonly used (1.0-3.0mm) edge is relatively difficult, but some parts are not visible on the use of the thin edge of the (0.4-1.0mm) can be straight, curve processing. Usually manual and automatic edge banding machine with straight edge machine generally used to meet product requirements, while only a straight edge for the product will improve efficiency, reduce production costs.
In order to achieve a stable curve edge high quality level, we need a CNC machining centers or CNC edge banding machine, both machines for some special sealing surface can show special advantages, such as the use of edge can make the circle with the length of the counter the smallest gap edge docking, more suitable for manufacturing high-end furniture products. The difference is the processing center panel saw can cut from the elements forming the final parts of the whole process, and a dedicated CNC machine can only complete edge sealing and trimming process, the shortcomings of using the processing center is closed edge The total processing time occupies a larger edge, reducing overall productivity.
As can be seen from the above analysis, acquisition and use of edge banding machine should pay attention to product yield and ability to adapt to market requirements, choosing a different degree of automation equipment and combination.
Edge of quality by many factors, including equipment status, operational proficiency, raw materials, condition, etc., generally should pay attention to the following aspects:

a. Solid Edge not too high moisture content of materials, should be stored indoors in a cool and dry, dust-free substrate requirements, the best moisture content of 8-10%.

b. As the edge quickly, at low pressure to the adhesive has good permeability of the substrate and diffuse, have a good initial viscosity, in a short time under the pressure of the moment should be glued, bonded a solid. Use hot melt adhesive to be taken to ensure the temperature in the normal temperature range, long time high temperature will glue points; low temperature hot melt adhesive of any good liquidity, used to have a good supplier the data.

c. the amount of hot melt adhesive glue should be to make the outside a little out of plastic parts subject is too large, a black line at the edge, aesthetic impact; too small, the bonding strength is not enough. In order to test whether the continuous film, you can bring a transparent rigid PVC test; also used ordinary Edge of Edge, will take advantage of plastic is not cool to test the edge of the tear.

d. can not be processed at room temperature is too low, should normally be more than 15 ° C, especially when the edge of the thick, flexible enough and, to ensure the normal operation of preheating devices, without pre-heating hair dryer can be used when heating methods such as the Edge with softening, the curve of the method is especially suitable for sealing. Processing plant shall not have Guotang Feng.

e. Edge of the quality of the impact of edge effects, edge of the seal of good quality products at the edge tight, poor quality products out of sealing edge of the gap edge at large, there is a clear black line . Trimming machine when backing easily scraped off the surface trace. Thick edge band from the cross-section view, the cemented surface in the middle should be slightly concave on both sides than some of the edge of the seal at the edge of the product more closely, the effect is good.

f. sealing machine for use without prior milling device manufacturers, to be semi-finished cutting edge quality also affect the edge effect. General product manufacturers in order to prevent explosive edge, cutting saws will use the notch (commonly known as a small saw blade), cut after the best results should be able to see a small section at the saw blade marks, but feels they feel. Saw marks too small when the sealing edge is not strong, visible at the edge or even see a black line gap, shallow and explosive mouth.

g. with the thick edge of the edge, the edge pressure roller tension machine should be adjusted to the optimum position, most likely a mistake is the weight of too tight. As the edge with slightly longer than the workpiece, when the pressure roller press and hold the edge with a grown part, to the edge of a perpendicular to the feed direction of the force, this time due to not fully cured adhesive, bonding strength is not high, Easy release and stick the tail is not strong.
