What materials are needed to make a showcase, the technological process of making a showcase, and how to distinguish the quality of a showcase?

Wooden showcase is the most popular type of showcase in the exhibition industry. Because of its own advantages, many merchants use wooden display cabinets. Here is some common sense about wooden showcase.

Window material

Wooden display cabinets are divided into solid wood display cabinets and plate display cabinets. The commonly used materials for solid wood display cabinets are beech, maple and oak. The commonly used materials for flat display cabinets are particleboard, density board, plywood, large core board, melamine board, fireproof board, etc.

According to the surface treatment, there are spray painting, plastic absorption, melamine, fireproof board and so on.

Classification of coatings for wooden display cases

1: polyurethane

Features: environmental protection, adhesion, sealing, flexibility and transparency of paint film are all advantages.

2: PE (unsaturated resin paint)

Features: high hardness, fullness, transparency and good filling.

3: CNC class

Features: quick drying and simple operation.

Common connecting materials for wooden display cabinets

1: nails

2: Glue

All-purpose glue, white latex (special glue for materials)

Three in one, wooden tenon, door hinge, guide rail, etc.

Drawing requirements of samples

1. Translation

2. Three views (including various sizes, materials, brands, grades, surface treatment, assembly methods, local enlarged drawings at nodes, as required by expression).

Key points of drawing inspection

1) Can you see the dimensions of the product?

2) Can you see the specifications and dimensions of each component?

3) Can you see the positioning dimensions of each component?

4) Can you see the core material requirements of each component?

5) Can you see the surface requirements of each component?

6) Can you see the link pattern of each component?

1. Main construction technologies

(1) varnish construction technology:

Clean the wooden structure surface of the counter display cabinet → Sandpaper grinding → Moisten powder → Sandpaper grinding → Full scraping of putty for the first time, Sandpaper grinding → Full scraping of putty for the second time, Fine sandpaper grinding → Paint painting for the first time → Brush colored putty, Fine sandpaper grinding → Brush painting for the second time, Fine sandpaper grinding → Brush painting for the third time, dry indoors, and water sandpaper grinding → Polishing.

(2) Construction technology of mixed color paint:

First, clean the dust and wood burr on the base surface of the counter display cabinet, repair the base → smooth the wood surface with abrasive paper → brush the scar → render putty → brush drying oil → scrape the putty for the first time → polish → brush the primer → brush the surface layer → repair the putty → polish the topcoat for the third time → brush the paint for the second time → polish and polish the topcoat for the third time → polish and wax. ?

2. Key points of construction?

Code for construction of cleaning and oil injection?

Polishing the base layer is an important process of spraying varnish. First of all, it is necessary to remove impurities such as dust, oil pollution and sawdust on the surface of the counter display cabinet.

Lubricating oil powder is also an important process of varnish coating. During construction, cotton silk is dipped in oil powder and coated on the wood surface of the counter display cabinet, and rubbed back and forth by hand, and the oil powder is rubbed into the wood eye. When spraying oil, you should hold the oil gun easily and naturally, and exert force gently with your fingers to avoid loosening or shaking when moving. When spraying, it is required to soak more oil, less oil every time, operate frequently, in the same direction, and carry out construction according to the operation method of first up and then down, first easy and then difficult, first left and then right, first inside and then outside, and horizontal spraying and vertical spraying.

Code for construction of mixed oil on the surface of wooden display cases

At the grass-roots level, in addition to cleaning up the impurities on the surface of the grass-roots level, local putty should also be filled and polished along the wood grain with sandpaper. Before painting the top coat, seal the knots and wood resin with lacquer flake (shellac paint). Drying oil should be painted or parked at the grass-roots level, and drying oil layer should be sprayed evenly, without missing spray. After the priming oil is completely dried, scrape the putty for the first time, polish it with manual sandpaper after drying, and then fill in the high-strength putty. Putty shall be based on not picking silk. When spraying topcoat, it should be polished with fine sandpaper first. ?

3. Precautions?

(1) The base treatment shall be constructed according to the production requirements of display cabinets, [because the painted display cabinets have various effects, such as matte/semi-matte/bright/open, etc. ] Ensure the production effect and achieve the surface painting and design effect. ?

(2) Before spraying, the surrounding environment should be cleaned to prevent dust flying and maintain a clean spraying environment.

(3) Because the paint is toxic and has a strong stimulating effect on human body and respiratory tract, attention must be paid to ventilation and self-protection during construction.

Sample cycle of wooden showcase

1. painting (procurement time+carpentry production time (1-4 days)+surface treatment time (3 days+rework time 1 day), and the general reply delivery time is 5-8 days.

2. Non-painting (procurement time+carpentry production time (1-4 days)+trial assembly (1 day), and the delivery time is generally 2-5 days.
