We are well aware of the problems faced by those involved in the production of molds for plastic. The processes required to arrive at the final solution can dramatically affect times and costs. For this problem you need a reliable plastic injection molding manufacturing.
Generally, an injection mold consists of many complex cavities, inserts and cooling channels.
Relevant Costs and Times
Making an injection mold with traditional methods involves high tooling costs and long delivery times.
Mold tools must be able to withstand repeated impacts and exposure to high temperature polymers.
Similarly, improving the overall efficiency of the process is essential to preserve margins and meet the deadlines set by customers and in this, professional plastic injection molding manufacturing represents a reliable ally.
3D printed molds and inserts are much cheaper, easier and faster to make. Moreover, using a 3D printer in making injection molds makes the whole process more efficient.
Additive technology in plastic or metal allows obtaining complex geometries and cavities in a simpler way, avoiding complex manual processing.
The cost of making a mold is often influenced by the need to make changes to achieve the desired final result. Similarly, the 3D printing makes the most economic process.
Metal and polymers resistant to high temperatures and mechanical stress to make additive molds that resist wear in short cycles. In addition, start your journey to improve efficiency through 3D printing today.
Reduce the material used and build lightweight inserts while maintaining wear resistance with a Desktop Metal 3D printer. Furthermore, it improves part quality and reduces cycle time, lowering costs and increasing productivity.
Basically, PolyJet ™ technology is a 3D printing method that allows companies to build in-house injection molds, quickly and easily. Moreover, it uses liquid photopolymers that gets the shape of desired geometry.
We can position prototypes using plastic injection molding manufacturing efficient way. Furthermore, it is good to create prototypes of the same material required for the finished product.
These precision prototypes provide realistic examples of finished products and can be used to collect actual performance data in real-world applications.
When you have a project in mind, be it large or small, creating a prototype is definitely an important step to take. Doing a test before going into production, in fact, minimizes the possibility of evaluation and calculation errors which, if not discovered in time, would lead to waste and costly rework.
In particular, the so-called rapid prototyping with 3D printing comes to the rescue in plastic molding projects. It is a set of industrial techniques useful for creating a prototype, in a relatively short time, starting from a three-dimensional mathematical definition of the object (CAD).
Having a prototype of the object you want to produce allows you to carry out various preventive tests , so as to verify its ergonomics, functionality, assembly, aesthetics.
3D prototypes in plastic molding projects therefore have several advantages:
A realistic prototype also represents a very effective tool for marketing actions and can be useful to all the different company areas to have a more concrete vision of the project: from Research and Development, to the Technical Office, to Marketing, to Production.
In whole process you need professional plastic injection molding manufacturing.
The techniques for creating prototypes are numerous using plastic injections molding manufacturing. The ones we usually use are those illustrated below: according to the different needs of our customers, we direct each project towards the most suitable technique.
The technology called Multi Jet Fusion (acronym MJF) employs a printhead of the ink jet nozzles to selectively apply melting agents and detail on a nylon powder bed. The fusing agents give heat to the material by melting the particles to allow the creation of a solid layer.
After each layer is created, the powder is redistributed on the bed and the process repeats until the piece is complete.
This process allows for a good surface finish, small details, reliable mechanical properties and short lead times.
Polyjet is a technology quite similar to MJF: also in this case molding heads are used and for this the final result is quite similar.
The main difference is in the removal of excess materials and support structures to arrive at the final geometry.
Plastic injection molding manufacturing technique gives precise and detailed results, but is not suitable for large quantities of parts.
Using a laser radiation as in stereolithography, in the case of sintering the construction material, that is the nylon powder, is aggregated by a heat adduction that melts the particles stably, solidifying them.
This technology allows building parts with very complex geometries and with small details. The material is mechanically and heat resistant and can be further processed (eg painting and assembly of threaded inserts).
The construction process in Fused Deposition Modeling is based on the deposition of material by an extrusion head which, layer by layer, creates the object. Various materials can be used according to requirements.
The plastic injection molding manufacturing technology allows to create both aesthetic and functional prototypes, as well as to realize small productions thanks to the excellent properties of the materials that can be used.
Listening to the needs of our customers, we know how to best address each project, so as to create prototypes that reflect the physical-mechanical characteristics of the piece as much as possible , before moving on to mass production.
