Leave all the interior fittings, cases, and everything to us!

The Sanpelca series has different numbers based on density (specific gravity), with L-1400 (14 times) < L-2500 (25 times expansion) < L-3000 (30 times), meaning that smaller numbers indicate higher density and firmness, while larger numbers indicate lower density and softness. It is possible to cut the material into shapes that fit the case and contents, as shown in the photo. Additionally, we can also accommodate orders for the outer case itself, so please leave the entire case to us.

News about this product(1)

Sanpelca series case inner pads available for consultation from small quantities to mass production.

  • Product news

We are capable of producing case interior pads using the Sanpelka series. These materials are adopted as interior padding for cases with the purpose of protecting and securing the stored items, and we can accommodate a wide range of projects from small-scale prototypes to mass production. Case interior pads refer to the foam that is placed inside cases used for storing tools, precision instruments, measuring devices, and more. By processing the foam to match the shape of the stored items, it helps to mitigate impacts during transport and storage, and prevents the items from moving within the case. The Sanpelka series is made of relatively firm foam material and is commonly used for case interior pads. ■ Product Specifications Material: Sanpelka series Application: Case interior pads Compatible Shapes: Processed to match the shape of stored items Processing Methods: Die-cutting, bonding, shape processing Production Support: From small-scale prototypes to mass production ■ Processing Details We can accommodate everything from simple cut shapes to complex storage shapes, and we can also handle structures that combine materials of different thicknesses or bonding. We will propose appropriate processing methods based on quantity and application.
