Do you inspect a part if I only have a photo?

Yes. A clear photo plus one or two key dimensions is enough for a feasibility check. For final production we ask for the physical sample so we can 3D-scan it, separate worn from functional surfaces, and build a CAD model from real geometry.

What tolerance can you hold for reverse-engineered parts?

CNC machined metal and plastic parts are held to plus or minus 0.05 millimeter on critical features and plus or minus 0.1 millimeter general. 3D-printed prototypes are typically plus or minus 0.1 to 0.2 millimeter. Rubber and silicone molded parts are verified by first article inspection to functional fit.

Do I get a material certificate with a replacement part?

Yes, when material matters. For production parts we can provide a material certificate of analysis, hardness test report, XRF material identification when the original datasheet is lost, First Article Inspection report, and a scan-to-CAD deviation summary.

What if the original discontinued part is badly worn or broken?

We do not copy a worn surface blindly. We identify datums and mating features, separate worn surfaces from functional ones, reconstruct the intended geometry from symmetry and standard sizes, and confirm reconstructed dimensions with you before production.

Can you improve the original design during reverse engineering?

Yes, within reason. We commonly upgrade material grade and weak sections while keeping mounting patterns, shaft sizes, bolt circles, and interface dimensions OEM-correct unless you request a change.

Do you do one-piece prototypes for obsolete parts?

Yes. Most reverse-engineering jobs start with one piece: 3D scan, CAD reconstruction, single CNC or 3D-printed unit, fit check on your machine, then small batch. Minimum order quantity of one is standard for discontinued spare parts.

How fast can a reverse-engineered part be ready?

Most mechanical parts are ready in 7–15 business days after sample receipt. Rush service (3–7 business days) is available. Electronics-adhesive die-cuts often ship faster.

Is a reproduced part as good as the OEM original?

In most cases yes, and often better. We can upgrade material grade, tighten tolerances, or improve surface finish based on how the part actually wears. Dimensional inspection reports ship with every order.

What if the OEM released a revised version after mine?

We can incorporate the OEM's design revision into your reproduction—without the OEM lead time, tooling cost, or minimum order quantity.

Can you make multiple copies for spares?

Yes. Most maintenance teams order 3–5 units: one for immediate repair, the rest as strategic spares to avoid repeat downtime.

What is the minimum order quantity?

One piece. We regularly produce single-unit reproductions for legacy equipment with no OEM support, plus low-volume runs of 10–50 pcs.

Sony A7 Body Waterproof Gasket — EPDM Seal

Custom reverse engineering, non-drawing part reproduction, and complete internal auxiliary material kits for legacy, discontinued, and new electronics.

Sony A7 Body Waterproof Gasket — EPDM Sealing Strip for A7M3/A7M4/A7C/A6400/RX100

Sony does not supply body waterproof gaskets as separate service parts for A7 series cameras. After camera disassembly (sensor cleaning, shutter replacement, grip repair), the EPDM gasket around the lens mount and body joints is destroyed. Water and dust then enter the body.

MoreMaking reproduces EPDM sealing gaskets for Sony A7M3, A7M4, A7C, A6400, and RX100 series. We non-destructively scan original donor bodies, rebuild gasket geometry, and cut closed-cell EPDM foam. Each set includes lens mount seal + body joint strips + viewfinder light-blocking foam.

Bullet Points

• Closed-cell EPDM foam, matched to Sony original spec
• Full set: lens mount + body joints + viewfinder foam
• Fits A7M3/A7M4/A7C/A6400/RX100
• Restores dust/moisture resistance after disassembly
• Also for Fujifilm XT4/XT5/X100V (separate SKU)

FAQ

Q: Will this restore dust/moisture resistance?
A: Yes, installed on a clean dry body.

Q: Does it fit A7M2 / A7R3?
A: Yes, different SKU — check compatibility list.

Q: How long does installation take?
A: 1–2 hours for an experienced technician.
