Common knowledge of PVC foam board processingCommon knowledge of PVC foam board processing
The processing performance of PVC foam board is the same as wood. There is one thing to pay attention to in the hollow cutting of the foam board. Because the hollow spacing is 23㎜, if you do not pay attention to the cutting, multiple pieces are overlapped and cut at one time, causing the difference in spacing; you can use the fixture to position it in the manner of a pin , Easy to process, below I will introduce to you the common sense of PVC foam board processing in detail:
1. You can use the engraving machine to form according to the design drawing, and then select the surface to be pasted with Mena or baking paint; but the hollow foam board needs to be noted that if the surface is uneven, only the vacuum overmolding method can be used. The material is 2㎜ PVC board.
2. Bending forming is only applicable to solid foam board, hollow foam board is not suitable; the processing method is to use the upper and lower molds, cover the wooden mold surface with aluminum plate and heat the solid foam board to the plasticizing temperature of 70~90℃ In the meantime, the shape of the foam board directly extruded by the upper and lower molds will not change.
3. When self-adhesive PVC is extruded and manufactured, the surface can be provided with wood grains with different textures printed according to requirements, which can save unnecessary processing procedures.
4. The surface of the PVC foam board can be painted, and the general category can be divided into general baking paint, piano baking paint and ceramic baking paint according to the processing method; anti-UV components will be added during the piano baking paint processing to avoid changes in the surface color; In terms of surface hardness, ceramic baking paint is also used as an excellent anti-scratching advantage.
5. Secondly, it is a common processing method. On the surface, a crystal plate (usually a single-sided colored acrylic plate), Mine board and Mina paper are used. In the edge-sealing part, most of the general processing is automatic edge banding machine for Mainly, the automatic edge banding machine is divided into two types of roller type and crawler type, but when using hollow foam board, it is recommended to use a crawler type edge banding machine, which is less likely to cause unevenness after the surface edge banding, pressure adjustment It is also very important; the color of the foam board is also recommended to use a color similar to the surface-mounting material, to avoid obvious color difference when shrinking after being attached to Mine paper.
6. Drilling holes can be directly processed by NC machine. It can reduce the density and increase the air content of the foam board itself according to the needs of the application, so as to achieve the effect of heat insulation and sound insulation and increase the cost reduction. For example, the density of the 15㎜ foam board and the weight of the same volume of 10㎜ foam board same. At present, some manufacturers have applied foam molding to tabletop molding or large machine cover using vacuum forming, but it has a disadvantage that it is not easy to wear due to poor surface mold resistance.
