Crack-resistant Composite Wooden Doors and Their Manufacturing Methods

A manufacturing method of the crack-resistant composite wooden door, which comprises the following steps:

• 1) producing the core frame (101), and inserting the core plate (3) in the grooves (112) of the inside core frame (110) of the core frame (101);
• 2) fastening and installing the lock rail (113) in the hollow section of the left stile (103) and/or right stile (104) of the core frame (101). Then putting the filling section (111) into the hollow structure formed by the outside frame (109) and inside frame (110) of the core frame (101);
• 3) producing panel plate (2) according to the shape of the core body (1), leaving a surplus of 1-5 mm respectively at the outside edge (202) of plate (2) and the inside edge (203) of it's hollow-out section (201);
• 4) fastening and connecting the panel plate (2) and the core body (1), and doing the edge milling for the outside edges (202) of the panel plate (2) and the inside edge (203) of the hollow-out section (201) according to the sizes of the core body (1), so that the panel plate (2) will completely match the core body (1);
• The crack-resistant composite wooden door mentioned comprising:
• 1) core body(l);
• It comprising:
• (a). core frame (101);
• (b). the hollow section (102) which enclosed by the core frame (101).
• 2) panel plate (2);
• It comprising hollow-out section (201).
• 3) core plate (3);
• The core plate (3) is installed in the hollow section (102). The shape of panel plate (2) matches that of the core body (1), and the shape of hollow-out section (201) matches that of the hollow section (102);
• The core frame (101) mentioned comprises left stile (103), right stile (104), top rail (105), bottom rail (106);
• The core frame (101) mentioned includes an outside frame (109) and an inside frame (110), and in the hollow section which enclosed by outside frame (109) and inside frame (110) there is a filling section (111);
• The inside frame (110) comprising a groove (112), the width of the groove should match the thickness of core plate (3). Core plate (3) is inserted in the groove (112).
