EPP and EPS foam have distinct technical properties, and therefore are employed in different application areas.
Expanded polypropylene (EPP) has a low density and it has a high elasticity; it has low compressibility and a high deformation recovery rate. EPP is resistant to oils, acid and alkali chemicals, and solvents; it does not readily absorb water. In addition to being non toxic and tasteless, it can be recycled with very high efficiency with minimal performance degradation.
These properties make EPP applicable to the packaging industry, especially for products sensitive to shock during handling, such as electronics and medical devices; these same properties combined with its complete lack of toxicity make it very suitable for shipping food products as well. EPP is also employed in the manufacture of car parts, serving as the core material for bumpers as well as roof structure and other components.
Expanded Polystyrene (EPS) is a rigid and tough closed-cell foam. Its advantage lies in the ability to produce products with different densities, and to be made into sheets of varying thicknesses as necessary; this flexibility in design comes from its production process, in which polystyrene beads are placed inside the mold and expanded using steam and a blowing agent, typically expanding by around 4000 percent and filling the cavity in the mold to produce the required shape.
Like EPP, EPS finds many applications in packaging, but it is also used in refrigeration and the manufacture of daily necessities; it also serves an important role in construction, primarily employed as a structural insulator; its excellent thermal properties enable it to improve the energy efficiency of a building when used in the walls and floor of a building.
1. How much time do you need to quote?
Unless the product has a very specific construction usually a quotation for a mold is send the next day after we receive enquiry with all the necessary details
2. I would like to get a quotation but the product is not yet protected by patent. Can you guaranty that my idea will be sufficiently protected if I send it to you?
If you feel uncomfortable about protection of your idea, we can sign a non-disclosure agreement before you send us any data.
3. What do you need to make a quotation?
To make a quotation, which will be adequate and sufficiently competitive, we need 3 things:
a. Product drawing or 3D model data file or product sample. If none of these are available, we need at least an ordinary sketch with the most critical dimensions of the product on it.
b. What Kind of plastic resin you are going to use in manufacturing or an idea of the durability of the product (what the product is or does).
c. Estimated quantity of the product needed in a period of time (i.e. one month) and the idea of how many products in total you are going to make (estimated total sales).
4. How long does it take to build an injection mold?
It varies a little depending on product size and complexity of its shape, but generally in case of DML, a middle size molds are built in 30 days lead time
5. I would like to have my mold built faster than you quoted. Is it possible?
DML’s mold building lead-time does not belong to the lengthy ones. On special request from clients and depending on our work load it is some times possible to make mold faster though the advancement cannot be big, just a few days.
6. Is it possible without a visit in your company to know whether my mold is being built on schedule?
On client’s requests we are giving a detailed mold-building schedule and send weekly reports. The reports may have digital pictures that show the progress of work.
