EVA Case Hard Shell Construction by Bentley Yeung from OCase E-Commerce Ltd.
EVA Case Hard Shell Knowledge
I’m Bentley Yeung from OCase E-Commerce Ltd.
OCase Specialize in custom EVA molded cases for many years.
I’m a EVA case specialist.
Let’s talk about EVA case knowledge.
1. Hard Shell EVA Materials
EVA Foam is an extremely versatile product. It’s suiting a broad range of different uses and applications. It is an effective replacement for many materials. Like felt, neoprene, natural rubber, polyurethane foam, pvc foam, wood composites, mineral wool and fibreglass.
Because EVA Foam is used for so many purposes, it can be sourced from a lot of convenient places in slightly different forms. Some kinds will be denser or softer than others, some will have a texture on one or both sides, and you will find it in a wide variety of thicknesses.
2. Surface Materials and inside materials
The surface materials and inside materials are both optional.
OCase can choose a surface material from Humen Cloth Market.
Ballistics Nylon, Polyester, Lycra, Mutispandex, Canvas, Oxford Fabrics, Mesh, PU, Carbon, Genuine Leather, etc.
Inside material can be similar, velvet, felt, mutispandex, mesh, Microsuede, even PU leather.
Both surface and inside colors are optional.
You can choose a color from OCase Pantone Card.
4. Hard Shell Construction
OCase always make EVA cases by 5mm (Thickness) and 70-75 Durameter (Hardness). Sometime, we make OCase cases in a wide variety of thicknesses, from 3mm, 4mm, 5mm, 6mm, 7mm, 8mm EVA materials and also 75-80 Durameter of EVA hardness. We just want a case / bag much harder.
But sometime, we have to use 3-4mm thickness and 60-65 Durameter hardness of EVA material for molded insert (EVA Tray) because of specifications the EVA foam’s density.
Some of OCase clients always want to order some high quality EVA Cases. So we make a EVA Shell with four layers, Ourside Material, Molded EVA, Memory Foam and Inside Lining.
Sometime, OCase case only has 3 layers, even 2 layers with a very competitive price.
5. Hard Shell 3 Layers Lamination
Like the OCase factory picture, we’ll laminate surface material, EVA foam and inside material together with Environmental protection glue using OCase Lamination machine.
By the way, all OCase raw materials comply with ROHS and Reach compliance. And OCase factory has also passed ISO9000 Certification.
At next blog, I'll talk about next step after Lamination.
It's Hot-Press Molding and it's the most important procedure for making an EVA case.
