Sintering furnace technology in the e-cigarette industry

---

Electronic cigarette (Electronic cigarette or E-cigarette), also known as Electronic cigarette, Electronic cigarette, virtual cigarette, Electronic cigarette atomizer, is mainly used to replace cigarettes and assist smoking cessation.E-cigarettes have become a significant trend in the tobacco market.

Looking into the future, the sintering technology involved in the e-cigarette industry has become one of the leading innovative technologies in the new industry. Sintering technology refers to the processing program and sintering process system selected according to the characteristics of raw materials.It has a direct and important influence on the output and quality of sintering production.According to the internal law of sintering process, this technology selects the appropriate process flow and operation system, USES the modern scientific and technological achievements, strengthens the sintering production process, can obtain the advanced technical and economic index, guarantees the realization of high yield, high quality, low consumption.The production process has.Raw material mixing, feeding, injection molding, degreasing, vacuum sintering, conformation, polishing, PVD and other steps.

E-cigarette structure as below:

E-cigarette atomizers and their metal components, because the product is small, require high precision accessories.So MIM metal injection molding technology has played a major role in the e-cigarette industry.

Compared with casting, machining and pressing, MIM metal injection molding process is more efficient and precise.Because the metal powder injection molding products are very precise complex structural parts, size error, thin wall, hole thickness can achieve high accuracy.The advantages of the MIM process include complex shape, small size, and high output.

In the application of MIM process to realize the complex structure of accessories, the product surface can also be processed with various post-processing techniques, such as mirror polishing and PVD surface treatment, to achieve a variety of colors, types and effects can be customized according to customer requirements, flexible.

The most important parts of the MIM production line are feeding, injection machines, and the selection of degreasing and vacuum sintering furnaces.

SIMUWU catalytic degreasing furnace USES nitric acid or oxalic acid to remove POM by the degreasing method of nitrogen atmosphere charging and washing, which is safe and reliable. Compared with solvent degreasing, it has the advantages of larger yield and smaller performance.

The following are the degreasing furnace specifications of different specifications:

Model	Temperature Uniformity Size(W*H*L)	Valid Capacity	Max. Temperature	Heating Power	Catalytic Medium	Working gas
CDF-335	350*350*500mm	100L	150℃	7Kw	HNO3	N2
CDF-446	450*450*670mm	220L	150℃	9Kw	HNO3	N2
CDF-669	650*650*920mm	630L	150℃	15Kw	HNO3	N2
CDF-4410	425*425*1000 mm	300L	200℃	16KW	HNO3	N2
CDF-5512	1260*503*530mm	600L	200℃	25KW	HNO3	N2

In addition, the SIMUWU vacuum sintering furnace has nitrogen, argon and hydrogen gas in different atmospheres, which can be customized according to different processes.

The use temperature of MIM sintering generally does not exceed 1300℃, and the equipment with the highest temperature of 1400℃ can be designed.Or customize SIMUWU standard RVS-M series vacuum debinding and sintering furnace.
