Furniture 32mm System Introduction 32mm System is an industrial standard which has been agreed by furniture and furniture fittings manufacturers. It originates from the center to center spacing of the drill pattern. 1.Hole diameter: Ø5mm 2.Hole spacing: 32mm 3.Distance between center of hole line and front edge of side panel: 37mm 4.Distance between rear hole center line and rear edge of side panel: 37mm
Furniture 32mm System Introduction 32mm System Basic Rules 1.Hole diameter: Ø5mm 2.Hole spacing: 32mm 3.Distance between center of hole line and front edge of side panel: 37mm 4.Distance between rear hole center line and rear edge of side panel: 37mm 5.The first and last hole in a hole line should be the same distance from the top and bottom edges of side panel 32mm System Advantages 1.Suitable for mass production, improve production effectiveness, reduce cost 2.Improve hole position accuracy, improve furniture quality 3.Furniture fittings interchangeable from different manufacturers 4.Make DIY easier

Drawer Runner Classification The type of runner is determined by the design of the running elements. Guide rails: Plastic rails act as gliding surfaces that support the weight of drawers and their contents. Roller-guided drawer runners: The running elements are rollers. The type of roller varies from friction bearing mounted nylon rollers to ball bearing mounted nylon rollers, ball bearing mounted nylon-coated steel rollers and silent moving rollers. Ball guided runners: Steel or plastic balls in ball cages are used as the running elements. Concealed dynamic runners: Rollers in running gear are used as the running elements. Drawer runner classification rules
Drawer Runner Classification Drawer runner terminology 1.Load bearing capacity The maximum load per runner pair. It’s a function of shape, metal thickness and length. Rated using a 18”(450mm) drawer runner. 2.Drawer runner length The longest dimension of a fully colosed runner 3.Half extension: runner opens partially, approxiamately ¾ runner length 4.Full extension: runner opens the same length as the runner length 5.Overtravel: provide an extra extension beyond the normal extension of a full extension length 6.Self-closing: drawer automatically closed approximately 50mm out from the front as it is being closed
Test procedures and requirements Drawer Runner Quality Level Three sets of extensions shall be used First set shall be used for Overload test Second set shall be used for Functional test Third set shall be used for Corrosion test 1. Overload test During test, the extension element shall be loaded according to the load bearing capacity 1.1 Vertical downwards static overload F=load bearing capacity but not higher than the maximum force specificed in test parameter Carry out 10 times
1.2 Horizontal sideways static overload 1.3 Outwards static overload F=50% load bearing capacity but not higher than the maximum force specificed in test parameter Carry out 5 times each direction F=200N Drawer Runner Quality Level
1.4 Slam-shut/open Velocity=1.0/1.3 m/s 10 times for shut and open 2. Functional test During test, the extension element shall be loaded according to the load bearing capacity 2.1 Operating force When the load bearing capacity is less than 40kg, the open and closing force shall not exceed 50N When the load bearing capacity is >= 40kg, the open and closing force shall not exceed 12.5% of load bearing capacity Drawer Runner Quality Level
2.2 1st Vertical downwards static overload F= 25% load bearing capacity but not higher than the maximum force specificed in test parameter Carry out 5 times each direction 2.3 1st Horizontal sideways static overload F=50% load bearing capacity but not higher than the maximum force specificed in test parameter Carry out 5 times Drawer Runner Quality Level
2.4 Durability Grade 1: 20,000 cycles Grade 2: 50,000 cycles Grade 3: 80,000 cycles (if loading capacity is >15kg: 60,000 cycles Premium grade: 100,000 cycles (Blum standard) 2.5 Deflection of front The deflection shall not exceed 4% of the extension length
Drawer Runner Quality Level 2.6 2nd Vertical downwards static overload F= 25% load bearing capacity but not higher than the maximum force specificed in test parameter Carry out 5 times each direction 2.7 2nd Horizontal sideways static overload F=50% load bearing capacity but not higher than the maximum force specificed in test parameter Carry out 5 times
2.8 Operating force When the load bearing capacity is less than 40kg, the open and closing force shall not exceed 50N When the load bearing capacity is >= 40kg, the open and closing force shall not exceed 12.5% of load bearing capacity Drawer Runner Quality Level 2.9 Slam-shut/open Velocity=1.0/1.3 m/s 10 times for shut and open
3. Corrosion test Drawer Runner Quality Level EN ISO 6720-2: Paints and varnishes - Determination of resistance to humidity - Part 2: Procedure for exposing test specimens in condensation-water atmospheres Requirement: 3 cycles AHT EN ISO 9227: Corrosion tests in artificial atmospheres —Salt spray tests Requirements: 24 hrs (general products) Ra/Rp=7/9 48 hrs (premium products) Ra/Rp=7/9
Drawer Runner Quality Level 4. Other requirements( not included in DIN EN 15338-2007) 1.Surface requirements: surface dent mark, scratch, burrs etc. should controled in a certain limit 2.Smoothly open and close, don’t have big noise 3.Extensioin length accuracy 4.Gaps between case, drawer member shoube be in a certain limit 5.Package: retail package or bulk package retail package: 1 pair in one polybag or in one box, include accessories buld package: 20-30 pairs in one carton box, include or don’t include accessories 6.

Package Retail Packaging Repon offers retail packaging as required for certain markets. A specialized example of such a pack would be product for the computer server market. A computer server kit, for example, would contain a single pair of slides ( L hand & right hand ) along with a pack of screws, mounting brackets and quick installation. Standard slides, too, can be individually poly bagged along with a packet of screws for retail sales. Distribution packaging Repon provides the wholesale distributor with the kind of packaging he requires for his cabinet shop customers. A typical example would be: 15 pairs of drawer slides, each pair in its own polybag, packed together in a strong cardboard master case.
Production Packaging Repon provides production packs for customers who use drawer slides on a larger scale beyond what could be served by a standard distribution pack. Also called a “ factory pack ” Repon ’ s production pack would typically have all right-hand drawer slide member in one large master case and all left-hand members in another large master case. Cabinet members and drawer members are also typically packaged separately. Production packs vary greatly, according to product type and customer ’ s own factory requirements. In many cases, production packs are custom designed per customers ’ individual needs.
Bulk packaging Repon offers a variety of bulk packaging — including “ gayloard ” packs — for very high-volume customers. Slides are typically packed more than 300 pieces per crate. These large crates can be made out of wood or super heavy-gauge corrugated cardboard, depending on product weight/type and customer requirements.
