The first selection.
At present, China saw acrylic sheet, basic imported or joint venture production, the quality of plates can be said better. Tuoyuan plexiglass acrylic plastic light boxes reason why higher market price, the higher the price sheet is one of the main factors. Currently on the market in general that the acrylic sheet Price 5-30 yuan / kg, only high unit price, resulting in significant cost amortization. After the material is decided, then immediately required to determine the appropriate size boxes need to be clear: the limited cast acrylic sheet length, up to 3-3.5 meters; acrylic sheet extrusion board supply available in the form of the theory length unlimited acrylic panels can be made out of a long length seamless light box signs; as estimated by cast acrylic plate, generally require stitching oversized light box signs, the role of wind pressure may be deformed General formal acrylic sheet manufacturer will provide the appropriate product specifications.
The second mold production.
As we all know, acrylic plate by vacuum positioning, suction molding, even with a word, different sizes need different molds, and molds itself requires precision quality good. Because the mold itself, precision, quality is directly related to the quality of acrylic products, and mold production have higher level of technology, it requires experienced technical staff. Therefore, as described above, the current market high-priced brand light box has been, mold processing should be said that the most important costs.
The third post-production.
Recall, now acrylic plastic production is basically mechanized production, the application of some new equipment to improve productivity while reducing the large labor intensity. Acrylic plastic material after the basic shape, but also through milling, engraving and milling, grinding and other several processes, and finally laying light boxes, produced after baking.
The fourth picture processing.
According to the different needs of customers, the picture is transferred directly by screen printing onto acrylic sheet, after vacuum molding, wherein the picture in person or animal or product image, but also re-established plastic body effect, thus get more good publicity.
Boxes production process:
(1) making molds, molds are common wood mold, but also with portable reciprocating data (about the price of 200-1000 yuan) production molds.
(2) mold deep processing: grinding, trimming, smooth mold formation.
(3) mold plastic platform location, male and female molds aligned position coincides fixed.
(4) The acrylic sheet is heated, plastic equipment common host temperature upper limit set at the lower limit of the system at 70 ℃ 150 ℃.
(5) soft acrylic sheet is heated to reach the desired temperature change, on (I type, type Ⅱ) plastic suction molding platform.
(6) After forming the semifinished acrylic panel, by a milling machine milling off the excess edges.
(7) Acrylic panel with acrylic word splice (Note: Only for acrylic word boxes without this step).
