How to cut hard plastic at home
Cutting plastics can be challenging. Matching the tools to the type of plastics you have requires foresight and knowledge of the physics of cutting. However, you can simplify your life by using ready-made guides. One of them is published below, taking into account the most important characteristics of different plastics.
The ease (or difficulty) of cutting a given material is due to the specificity of the material itself and the operating characteristics of the tool used. To say that hard plastic is difficult to cut is an understatement: concrete is also difficult to drill with a wood drill, but seemingly easier to process wood will not suffer concrete drills.
Plastics are for the most part quite flexible. This alone is already an obstacle to convenient machining. The thicker and harder the material, the more rigid it is, the less it resists cutting, but you must use another tool to tear the top layer. Some plastics are also quite sensitive to high temperatures, others become brittle again at low temperatures; all this determines whether it is easy or difficult to cut.

Due to their versatility, metals are used in areas of application such as mechanical engineering, construction or steel construction. These are just three of the many sectors in which waterjet cutters are used.
Since these are composite materials that are light and stable, they are used in particular in lightweight construction and in the aerospace industry. These are sectors that need these requirements.
Yes, the cutting speed varies greatly depending on the material, hardness and thickness, but the desired quality of the cut (from fast coarse sectioning Q1 to slow fine cutting Q5 with angle correction of up to +/- 0.01 mm), the water pressure and the amount of cutting sand used also affect the speed.
In the case of brittle materials, low-pressure punching can be used in conjunction with our systems to punch holes gently so as not to cause chipping. The cutting path can be automatically switched to the fast high-pressure mode.

Some of them are graduated or single-flush, i.e., they are filled once at zero milliliters, and then allowed to drain to the required volume; in others, the so-called double-flush or double-gauging pipettes, the liquid is filled at the upper mark or gauge and allowed to drain carefully until it is flushed into the lower gauge. Although they have the disadvantage of measuring a fixed volume of liquid, the double-gauging pipettes greatly surpass the graduated ones in that their precision is much greater, since the volume measured does not change if the conical tip is broken or deformed. In order to perform the liquid suctions with greater precision, the device known as the propipeta is used, more than anything else in the double volume pipettes..
Plastic cutting tool
It is a glue for plastic most used by experts, as it is of high quality and offers a great guarantee from the manufacturer. One of its main features is that it is transparent, so once it is applied it cannot be seen.
It also falls into the category of water-resistant plastic glue, so it can be handled in the rain and come into contact with water without any problem. It usually dries in just 10 minutes.
It only takes 3 seconds to dry and bond the pieces together, so you have to be very fast during application. However, to obtain great results it is important that the surface is clean and dry.
One of the best water-resistant adhesives is pattex nural. In only two minutes it is able to do its bonding effect; that is why it is advisable to be fast and precise in its application. And something important to mention is that it not only resists water, but most liquids, allowing it to adhere to nylon, PVC and ABS plastics.
It is a strong plastic glue ideal for restoration work, model making and model making. The best thing about this product is that it offers the opportunity to correct if the plastic does not stick well without leaving a mark.
