In the field of mold manufacturing,The accuracy and quality of the mold directly determine the quality and production efficiency of the final product。however,During the long-term use of molds,Unavoidably contaminated with various dirt,Like oil stains、iron filings、Resin residue, etc。These dirt not only affect the appearance of the mold,It will further reduce the accuracy of the mold、Shorten its service life,Even causing defects in the product。Traditional descaling methods often have low efficiency、Damage to molds and other issues,andDry ice cleaning machineThe appearance of,Bringing a new and efficient solution for rapid descaling in mold manufacturing,Here are several highly representative practical cases。

Case study of cleaning automotive parts molds

Mold contamination status

A well-known automobile parts manufacturing enterprise,After a period of use, the cylinder head molds produced by it for automotive engines,Accumulated a large amount of oil pollution、Iron filings and residual coolant。These dirt increase the surface roughness of the mold,During the injection molding process,Causing defects on the surface of the cylinder head,Like pores、Flow marks, etc,Seriously affecting the qualification rate of the product。not only ... but,Dirt also hinders the heat dissipation of the mold,Make the mold temperature uneven,Further exacerbating product quality issues。

The traditional cleaning dilemma

The company has been using a combination of manual polishing and chemical cleaning to clean the molds before。Manual polishing is not only inefficient, but also inefficient,And it is difficult to ensure the uniformity of cleaning,Easy to leave scratches on the surface of the mold,Affects the accuracy of the mold。Although chemical cleaning can dissolve some dirt,But chemical agents have a certain corrosiveness to the metal material of the mold,Long term use will shorten the service life of the mold。in addition,The treatment of waste liquid after chemical cleaning is also a challenge,Increased environmental protection costs for enterprises。

Dry ice cleaningapplication

To solve the problem of mold cleaning,The company has introducedDry ice cleaning machine。During the cleaning process,The operator sprays dry ice pellets onto the surface of the mold through compressed air。The low-temperature characteristics of dry ice particles cause rapid embrittlement of dirt,At the same time, the impact force generated by sublimation will peel off the brittle dirt from the surface of the mold。The entire cleaning process does not require dismantling the mold,Greatly reduced downtime。

Significant improvement in effectiveness

useDry ice cleaning machineafter,The cleaning efficiency of molds has been significantly improved,The cleaning work that originally took several days to complete,It only takes a few hours now。The surface of the cleaned mold is clean and smooth,The roughness returns to its initial state,The quality of injection molded engine cylinder heads has significantly improved,The qualification rate has increased from the original 80%Improved to 95%the above。not only ... but,Due to dry ice cleaning, it will not cause damage to the mold,The service life of the mold has been effectively extended,Saved a lot of mold replacement costs for the enterprise。

Cleaning case of electronic component molds

Mold contamination issue

A company specializing in the production of electronic components,The mold for producing precision electronic connectors is in use during the production process,Contaminated with a large amount of resin residue and tiny metal dust。These stains cause changes in the size of the mold cavity,Causing the dimensional accuracy of the produced electronic connectors to not meet the standard,Unable to meet customer requirements。meanwhile,Dirt may also cause safety hazards such as short circuits,Affects the performance and reliability of electronic products。

Traditional cleaning limitations

The company has attempted to use ultrasonic cleaning and high-pressure water gun cleaning methods to clean molds。Although ultrasonic cleaning can remove some dirt,But for some stubborn resin residues, the effect is not good。High pressure water gun cleaning may flush metal dust into the small gaps of the mold,Causing secondary pollution,Moreover, high-pressure water flow may also cause damage to the precise structure of the mold。

The advantages of dry ice cleaning are highlighted

introduceDry ice cleaning machineafter,The situation has significantly improved。Dry ice cleaning machine can accurately spray dry ice particles,Deeply penetrate the small gaps in the mold,Thoroughly remove resin residue and metal dust。Due toDry ice cleaningIt's dry cleaning,No wastewater will be generated,Avoiding the problem of secondary pollution。not only ... but,Dry ice pellets have lower hardness,Will not cause any damage to the precise structure of the mold。

Win win situation of quality and efficiency

pass throughDry ice cleaningafter,The precision of the mold cavity size has been restored,The dimensional qualification rate of the produced electronic connectors has reached 100%,Satisfied the high demands of customers。meanwhile,The shortened cleaning time increases the turnover rate of the mold,The production efficiency of the enterprise has been significantly improved,The production cost has also correspondingly decreased。

Household appliance shell mold cleaning case

Mold contamination status

A large household appliance manufacturing enterprise,The mold for producing refrigerator shells has been used for a long time,The surface is covered with oil stains、Residual release agent and rust on some scratched areas。These stains cause a decrease in the surface quality of the refrigerator casing,Spots appear、Color difference and other issues,Affects the appearance and sales of the product。not only ... but,The presence of rust may further corrode the mold,Reduce the strength and durability of the mold。

Traditional cleaning challenges

The company previously used traditional sandblasting cleaning methods to clean molds。Although sandblasting cleaning can remove dirt and rust,But it will cause significant wear and tear on the surface of the mold,Increase the surface roughness of the mold,Frequent polishing is required,Increased production costs and downtime。in addition,The dust generated during sandblasting can also cause pollution to the environment,Affects the health of operators。

Innovative application of dry ice cleaning

To improve the cleanliness of the mold,The company has adoptedDry ice cleaning machine。Dry ice cleaning machineDuring the cleaning process,Will not generate dust,Friendly to the health and environment of operators。meanwhile,Dry ice cleaning can selectively remove dirt and rust,Will not cause additional wear on the surface of the mold。For some difficult to remove rust stains,Dry ice cleaning machineIt can be cleaned multiple times and the spray angle can be adjusted,Thoroughly eliminate it。

Appearance and cost optimization

After using a dry ice cleaning machine,The surface quality of the refrigerator shell mold has been significantly improved,The appearance of the refrigerator shell produced is smooth、Uniform color,The market competitiveness of the product has been enhanced。not only ... but,Due to the reduction of mold wear and polishing frequency,The service life of the mold has been extended 30%the above,The production cost of the enterprise has been reduced 20%about。

Dry ice cleaning machineApplication prospects and promotion strategies

Wide application prospects

With the increasing demand for product quality and production efficiency in the mold manufacturing industry,Dry ice cleaning machineThe application prospects in the field of rapid descaling in mold manufacturing are very broad。It can not only improve the cleaning efficiency and quality of molds,It can also extend the service life of the mold,Reduce production costs and environmental pressure for enterprises。next,Dry ice cleaning machineExpected to become a standard equipment in the mold manufacturing industry。
