Abstract

The invention provides a manufacturing method of a ceramic shell with metalized edges. The manufacturing method comprises the following steps: cutting a casting sheet on the uppermost layer and a casting sheet on the lowermost layer in the ceramic shell in a set area through a cutting knife to form gaps; carrying out metal slurry printing on the cut casting sheet by using a printing machine, so that the slurry enters a gap; performing lamination according to design requirements, and performing hydrostatic pressing; and then manufacturing the ceramic shell through an existing process. The manufacturing process is simple and convenient, and the strength of the corners of the ceramic shell is greatly improved.

Description

Technical Field

[0001] The invention relates to a method for manufacturing a ceramic shell, in particular to a method for manufacturing a ceramic shell with metallized edges. Background Art

[0002] The existing ceramic shell is made by stacking multiple layers of cast sheets, laminating them, and sintering them. The four corners of the ceramic shell are all right angles. During brazing or sintering, it is easy to cause chipping due to stress. During transportation, since the ceramic is brittle, chipping may occur in the case of slight bumps. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a method for manufacturing a ceramic shell with metallized edges. The manufacturing process is easy to implement and improves the foot strength of the ceramic shell.

[0004] The present invention is implemented as follows: a method for manufacturing a ceramic shell with metallized edges, comprising the following steps:

[0005] Step 1, cutting the uppermost cast sheet and the lowermost cast sheet in the ceramic shell in a set area by a cutting knife to form a gap;

[0006] Step 2: Printing the cut cast sheet with metal slurry using a printer so that the slurry enters the gap;

[0007] Step 3: stack the sheets according to the design requirements and perform hydrostatic pressure testing; then complete the manufacturing of the ceramic shell using existing processes.

[0008] Furthermore, the cutting depth in step 1 is consistent with the thickness of the cast sheet.

[0009] Furthermore, the hydrostatic pressure in step 3 is 300-3000 psi; and the time required is 1 min-5 min.

[0010] Furthermore, the step 1 and the step 2 further include a step a, cutting a set area of ​​the cast sheet located in the middle of the ceramic shell by a cutting knife to form a gap.

[0011] The advantages of the present invention are: the present invention provides a method for manufacturing a ceramic shell with metallized edges. By adding metal slurry through the above method, the stress influence received by the ceramic shell during sintering can be eliminated during sintering, so that the corner strength of the ceramic shell is increased and no corner is chipped during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention will be further described below in conjunction with embodiments with reference to the accompanying drawings.

[0013] Figure 1 The present invention is a flow chart of a method for manufacturing a ceramic housing with metallized edges. DETAILED DESCRIPTION

[0014] See also Figure 1 As shown, the present invention provides a method for manufacturing a ceramic housing with metallized edges, comprising the following steps:

[0015] Step 1: Cut the uppermost cast sheet and the lowermost cast sheet in the ceramic shell with a cutting knife in a set area to form a gap; since the cutting knife is thin, the gap is closed in a static state; the set area can be the four corners of the cast sheet;

[0016] Step a, cutting a set area of ​​the cast sheet located in the middle of the ceramic shell with a cutting knife to form a gap; since the cutting knife is relatively thin, the gap is closed in a static state; the set area may be the positions of the four corners of the cast sheet;

[0017] Step 2: Use a printer to print metal slurry on the cut cast sheet so that the slurry enters the gap; under the action of the pressure of the printer, the gap will open, and the slurry will enter the side of the cast sheet along the gap;

[0018] Step 3: stack the sheets according to the design requirements and perform hydrostatic pressure; then complete the ceramic shell manufacturing through existing processes. Through hydrostatic pressure, the metallization on the ceramic side will become flat due to pressure.

[0019] In this embodiment, preferably, the cutting depth is consistent with the thickness of the cast sheet.

[0020] In this embodiment, preferably, the hydrostatic pressure in step 3 is 300-3000 psi, and the time required is 1 min-5 min. When the pressure is 300 psi, it takes 5 min; when the pressure is 3000 psi, it takes 1 min.

[0021] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
