Spuitgietverskaffers: effektiewe wenke om koste te verlaag

Spuitvorming is 'n uitstekende manier om koste-effektiewe onderdele of komponente te skep, mits u massaproduksie doen. Die spuitgietverskaffers gee 'n paar wenke om u begroting verder te laat rek.

Almal wil dieselfde produk teen 'n goedkoper prys hê. Dit geld ook in die vormbedryf. As u regtig belangstel om die totale koste van u gietvervaardiging te verlaag, het u op die regte plek gekom.

In this article, we are going to talk about some design recommendations that would reduce the cost of the entire molding process significantly. So, without any further delay, let us get started!

Also, have a look at the Injection Moulding Fields of Application in the Industry.

Injection Moulding Suppliers – Design Tips to Reduce Cost

The obvious way to reduce the price per unit is to increase the production quantity in injection moulding. After all, it is the upfront cost that is high, but once the machines are in place, everything is inexpensive. Higher the number of production units, the lesser the cost per unit would be.

But what if your product does not require more than a handful of components or parts. Let’s say, you just need 25 pieces. Getting this manufactured would cost your hundreds if not thousands of dollars. So, do you think to pay that much for just 25 pieces is worth it?

We don’t! Therefore, we suggest opting for cost-effective molds for small production quality.

How much would Injection Molding Cost?

There are several factors that affect the cost of the injection molding technique. The amount of time that it would take to produce a tool, is the main determinant of the molding cost. In simple words, we can say that if a part is complex, it would take more time to create it, thus the cost would be higher.

Simple parts that do not require advance surface finishes or undercuts, would be most inexpensive.

Note: Undercuts have the ability to complicate things. In some cases, they would even prevent part ejection. Therefore, it is best to eliminate them.

You also need to pay heed to the material that you are planning to use. It is going to have a direct impact on the per-unit price. There are some plastics that are easier to mold in comparison to others. Likewise, some plastics overlap in functionality and strength.

A good choice is to go with a material that is easy to mold as it would bring down the cost of every part.

So, here are the different injection moulding design considerations that will help in stretching the manufacturing price.

• Eliminate Undercuts
• Remove Unnecessary Features
• Neem kernholtebenadering in
• Reduce Cosmetic appearances
• Design Parts (Self-mating)
• Change and Reuse Molds
• DFM analysis
• Part Size
• Oorvorming

Undercuts

Ondersnydings kan lei tot die voorkoming van onderwerpuitwerping, sowel as om die funksies te bemoeilik. As u dit vermy, kan dit die kompleksiteit en die prys per eenheid verminder. Ons verstaan ​​wel dat dit in sommige gevalle miskien nie moontlik is nie.

Maar soek altyd na alternatiewe voordat u onderbesnoeiing insluit. As u byvoorbeeld 'n byaksie, 'n uitsluiting of 'n skuifafsluiting benodig, wat moet u doen? Probeer verskillende alternatiewe gebruik. U kan die deurlaatkern en die skuifafsluitings kies.

U kan ook die trekhoeke sowel as die afskeidingslyne verander om gladder vormvorming te verseker. Dit is klein, maar tog belangrike ontwerpveranderings. Dit sal 'n beduidende impak op die prys per eenheid hê, aangesien dit die siklusstyd van die masjien sal verminder.

OPMERKING: Die gebruik van die kernholte is 'n koste-effektiewe tegniek vir geribde oppervlaktes en die vorming van hoë mure.

Spuitgietverskaffers stel voor dat u onnodige funksies verwyder

Daar kan nie ontken word dat die maatskappy se logo's, gevormde onderdeelnommer en tekstuuroppervlaktes slim lyk nie. Hulle verhoog die prys egter dramaties. As dit nie 'n noodsaaklikheid is nie, moet u dit nie hê nie, veral met lae produksie.

Skakel alle nie-missiekritieke funksies uit. As u regtig die permanente artikelnommer moet hê, probeer dan die meulvriendelike lettertipe. Gaan byvoorbeeld saam met Verdana, Arial, ens. U kan u spuitgietverskaffers vra watter lettertipe dit verkies.

Neem kernholtebenadering in

If you require box-shaped parts such as the common home electronics, you have two options. Either can you use bring the aluminum material down around the core and then mold the required part around it. Or, you have the option of sinking the wall cavities into the mould base.

The former approach is the core cavity approach. It is inexpensive to the other approach. In addition, the core cavity approach ensures adequate venting, smoother surfaces, and improved ejection.

Reduce Cosmetic Appearance

Pretty Parts look good, but they would add more to the cost. The EDM, bead blasting, or the high molding polish would no doubt make the parts look smart, but they would drive up the tooling cost. If you need anything above the machine finish (PM-F0) it would require hand finish.

Dus, addisionele arbeidskoste, sowel as masjientyd. Dit is ook belangrik om die verskaffers te laat weet of u die helfte, volle of 'n sekere deel van die vorm wil poleer. As u slegs die benodigde oppervlakte poets, verminder dit die koste.

Selfparende onderdele

As u 'n ontwerp benodig wat aanmekaar klap, is dit beter om met een paringsdeel in plaas van twee te gaan. Probeer om paringsdele te bou wat die vermoë het om mekaar van beide kante te pas. Hierdie dele word gewoonlik die Universele onderdele genoem.

As u dit doen, sal die behoefte aan 'n bykomende vorm verwyder word. U het een vorm nodig om die hele produk te skep. Dit bespaar u dus die voorafgaande produksiekoste.

Gietvorms

Taking out metal from the exiting metal mold is easy. However, working with metal would be extremely difficult with rapid injection molding. Therefore, you can go with plastic. Do remember, you can add plastic, but it is not possible to take it away.

So, design while keeping this in your mind. Some of the injection moulding parts would go through several iterations before you finalize the design. Opting for a new mold every time is not a cost-effective solution.

Therefore, you need to design smartly. You should be able to use the mold over and over again. A good idea is to start with the basic part design mold. Then once you go on, add re0machine the mould to incorporate additional features.

DFM analysis

Good spuitgietverskaffers would accompany every injection mould part’s quote with a design for manufacturing analysis. It would high the possible problematic areas as well as the ways via which you can improve your design.

Few examples where you need to improve your part design include impossible geometries, un-machinable features, etc. Pay close heed to the suggestions as they will not only improve the design quality but also reduce the overall cost per unit.

Part Size

You need to pay close attention to the part extents. It basically means the size of your part and who well will it fit the mold. Would it allow for ejector pins, runners, sprues, and other similar considerations that are required for the mold to be operational?

You should ask the injection moulding suppliers for more details on the part sizes. They would provide you with their maximum and minimum part size requirements.

Oorvorming

Overmoulding is another aspect that can help you reduce production per unit cost. However, do bear in mind that it would cost you more upfront. For instance, you want to have a gasket on top of your part.

If you don’t add gasket upfront, the moulding would cost you less. However, when you have someone else to install it individually, it would cost you more. So, the better idea is to pay the upfront cost of the gasket by incorporating it into the moulding process.

Neem weg

Spuitvorming is 'n effektiewe en koste-effektiewe manier om onderdele en komponente te vervaardig, veral vir massaproduksie. Neem egter 'n paar effektiewe wenke in, dit is moontlik om die algehele produksiekoste van 'n beperkte aantal stukke te verlaag.
