How to control the quality of product inspection in solid wood furniture production?

Furniture quality standard is the main technical basis for manufacturers to organize production and test product quality, and it is also the time for furniture distribution units to check product quality and consumers to buy furniture

The main technical basis for judging the quality.

Furniture quality standard is the main technical basis for manufacturers to organize production and test product quality, and it is also the product quality control and consumer selection of furniture distribution units

The main technical basis for judging the quality of furniture when purchasing.

1、 Functional inspection of furniture

It includes the main functional dimensions of various products, such as the table height, middle clearance height, middle clearance width of table products, and the height difference of table and chair (stool) supporting products. according to

According to national standards, combined with enterprise product standards and user order requirements, the product warpage, footing stability, flatness, adjacent edge perpendicularity and position shall be inspected at the same time

The indexes of difference, joint separation, sag and swing reach the standard and allowable deviation range.

2、 Inspection of materials and materials for furniture

The materials should meet the national mandatory standards for the limit of harmful substances.

The tree germplasm used in the appearance of the product should be similar, and there is no obvious difference in the same glue piece tree species, and needle and broad-leaved wood are not mixed. The plywood tree species used on the surface shall be consistent,

Particleboard and medium density fiberboard shall not be mixed in a component composed of several parts.

The material of furniture requires that the moth eaten materials that have not been treated with insecticide and the insect holes that have not been repaired shall not be used; The area of rotten wood exceeds 15% of the part area, and the depth exceeds 25% of the material thickness

Shall not be used; Wood with twill degree exceeding 20% of the stressed part of the product shall not be used; Wood with knot width exceeding 1/3 of the width of visible wood and knot diameter exceeding 12mm

Materials shall not be used; Wood with through cracks and resin bags shall not be used; Those with local cracks, blunt edges and other defects that have not been repaired shall not be used.

3、 Inspection of product appearance requirements

The appearance requirements of products are the technical requirements for wood processing, finishing processing, and the installation of hardware accessories.

The products after wood processing are not allowed to have the following defects: the parts made of wood-based panels have not been edge sealed; There are degumming, blistering and patching after pasting the covering material

Seam separation and obvious glue penetration at the joint; There are looseness, seam separation and fracture at the joints of parts and components, mortise and hole joints, plate mounting parts and various supports; The appearance of the product is chamfered and round

Uneven and asymmetric lines and fillets; The lines of carving and turning wood are asymmetric, and the shovel bottom is uneven, with knife marks, sand marks, etc.

The finished products are not allowed to have the following defects: the whole product or a complete set of products have obvious color difference; The product surface coating has wrinkled, sticky and leaking paint film

Lacquered; The paint film coating has obvious fog, white ridge, white spot, oil white, sagging, shrinkage cavity, bristling, powder accumulation, miscellaneous slag, scratch, bubbling and peeling; Soft and hard overlays

There are dents, pits, scratches, cracks, collapse angles and cutting edges on the surface of the material; The parts of the product that are not painted and the interior of the product are not clean.

After the installation of hardware accessories, the products are not allowed to have the following defects: accessories are missing, and there are mounting holes missing mounting parts; Missing or penetrating nails of the installation parts; Moving parts do not start

agile; Accessories are not firmly installed or loose; Stubble chipping around the installation hole.

4、 Inspection of physical and chemical properties and mechanical properties of products

The physical and chemical property inspection items of wood furniture paint film include liquid resistance, damp heat resistance, dry heat resistance, adhesion, wear resistance, cold and hot temperature difference resistance, gloss, impact resistance, etc.

According to the service conditions of light load, medium load and heavy load, level 2, level 3 and level 4 test levels are selected for the standard, and the service conditions under special environment are agreed by the supplier and the demander.

The mechanical property inspection items include strength, durability and stability. The standard gives the five level test level of furniture in careful, light load, medium load, heavy load and overload use

Technical requirements under.

5、 Product packaging inspection

The packaging of furniture products shall meet the requirements of relevant standards, and the partial pressure test, landing test, vibration test and impact test shall be qualified. The manufacturer must sell products

Attached is the “furniture operation manual”, which should specify the variety, specification, model, structural characteristics, formaldehyde emission, moisture content of wood, mechanical properties and decoration of the furniture

Technical characteristics such as surface physical and chemical properties; It is necessary to indicate whether the main material of furniture is log material or inner core material, and the auxiliary materials include adhesives, coatings, hardware accessories, etc

Lattice; Indicate the control indicators of materials and coatings used for furniture containing toxic and harmful substances. Specify the unpacking inspection, installation and adjustment, use and maintenance, handling and storage, and failure of furniture

Requirements for analysis.
