제조 부품용 표면 마감 맞춤화
Specify what the surface must do: protect the part, control friction, carry identification or meet an appearance reference. A finish must suit the base material and leave critical fits usable. Mark visible areas, contact surfaces and dimensions that must be checked after finishing.
표면 마감은 사후에 고려하는 사항이 아니라, 기능적 사양입니다.
The finish must be specified against the actual material, manufacturing route, appearance target and service environment. Durability, sterilization compatibility, color stability and wear life require project-specific tests and acceptance criteria.
This page compares mold texture, as-machined surfaces and possible post-processing options so buyers can discuss a finish before production. Process availability, the execution route, finish limits, inspection method and any required sample approval are confirmed for the quoted part; the examples below are not a blanket capability or performance guarantee.

Mold texture and polish can affect the molded part, but replication depends on resin, part geometry and processing. Select a target finish during mold design review, then approve a physical sample against the agreed viewing and inspection conditions. Listed post-mold methods are options to discuss, subject to project confirmation.
| Finish option to review | Material and use | What to confirm before ordering |
|---|---|---|
| Mold polish or texture | Appearance molded into a compatible plastic part | Resin, target surfaces, draft, approved sample and inspection light |
| Printed or decorated graphics | Logos, symbols and labels on a compatible substrate | Artwork, adhesion, cleaning exposure and marking durability |
| Painting or coating | Color or protection where substrate and process permit | Adhesion, coating thickness, masking, exposure and sample approval |
| Laser marking | Part identification or graphics where the material responds suitably | Contrast, readability, location and any traceability standard |
| Metallization | Metal appearance or function on a qualified plastic substrate | Feasibility, adhesion, thickness, conductivity and required testing |
CNC 가공 표면 마감
CNC surfaces start as-machined. Mechanical, chemical and coating methods are options to assess, subject to material compatibility and project availability. Specify the target Ra and inspection area on the drawing.
가공 상태 그대로
Visible tool marks may remain. Specify any critical roughness value and measurement location on the drawing; achievable finish depends on material, geometry and toolpath.

SPI Mold Finish Groups — Selection Guide
SPI grade labels are a common way to describe a mold-surface target. The groups below are selection directions, not measured results for a quoted tool or part. Specify the target on relevant surfaces and confirm appearance and roughness with samples and an agreed method.
| SPI group | Typical mold-surface direction | Buyer approval point |
|---|---|---|
| A — polished | High-gloss direction | Confirm steel, resin, optical or cosmetic target and molded sample |
| B — semi-gloss | Fine stone or abrasive direction | Confirm visible areas and appearance against an approved sample |
| C — satin | Lower-gloss abrasive direction | Confirm texture, cleaning and visible surface zones |
| D — textured | Blasted or textured direction | Check draft, release, grip and replication on the selected resin |

Additive parts may show layer lines. The following post-processing options need a material-specific feasibility review and sample approval before they are included in a quote.
증기 스무딩
Chemical smoothing may reduce visible layer lines on a compatible printed material. Chemical compatibility, dimensional effect, surface target and availability require a sample review.
Layer-line reductionTest for sealing
Sanding & Priming
Sanding and primer can reduce visible layer lines before painting. Agree the target appearance and check any effect on critical dimensions on a sample.

Metallization is an option to assess for selected printed parts. Substrate preparation, coating adhesion, thickness, conductivity and any EMI target need a project-specific feasibility and test plan.

적합한 표면 마감을 선택하는 방법
도면이나 견적 요청서(RFQ)에 사양을 확정하기 전에 이 세 가지 필터를 사용하여 마감재를 선별하십시오.
주요 요구사항 정의하기
Is the finish cosmetic, protective, or functional? A mirror polish is a cosmetic choice; anodizing is protective; electropolishing may target cleanability when material and regulatory requirements permit. One finish can serve multiple goals — prioritize the most critical one.
재료 및 공정에 맞춰 조정
Not every finish works on every material. Aluminum anodizes beautifully; steel does not. Injection molded parts reflect the mold finish; CNC parts may remain as-machined or use a separate finishing step. Check compatibility before committing.
비용, 물량, 허용 오차를 균형 있게 조정하십시오
Compare tooling effort with per-part finishing work at the quoted quantity. Coatings and polishing can change dimensions or edge conditions, so mark critical fits and ask for the process allowance in the quote.
What affects a finish quotation?
Cost and lead time depend on the substrate, geometry, selected route, finish area, quantity, inspection and approved sample. A comparative chart cannot replace a project quote.
Identify the substrate
Provide the exact plastic or metal grade and the manufacturing process used for the part.
Mark the target surfaces
Call out appearance, texture or roughness, color, masking, critical fits and exposure conditions on the drawing.
Approve the evidence
Agree the sample, measurement method, acceptance criteria and required records before production release.
자주 묻는 질문
도면에 표면 마감을 어떻게 명시하나요?
가장 확실한 방법은 다음 세 가지 정보를 명시하는 것입니다: (1) SPI/VDI 등급 또는 Ra 값, (2) 예상되는 공정 방법, (3) 마감 처리가 필요한 표면. 예시: “캐비티 면에만 SPI B-1 적용” 또는 “Ra 최대 0.8 µm, 전기 연마, 모든 외부 표면.” “매끄럽게”나 “마감이 좋게”와 같은 모호한 표현은 재작업으로 이어질 수 있으므로, 항상 표준 등급을 사용하십시오.
투명한 플라스틱 렌즈에는 어떤 SPI 마감 처리를 해야 할까요?
A high-polish mold may be a starting point, but optical clarity depends on resin, mold steel, geometry, molding conditions and the viewing standard. Define the optical requirement and approve a molded sample before specifying the finish.
양극 산화 처리를 하면 부품의 치수가 변하나요?
Yes, and this catches many first-time designers. Anodizing changes the surface and can affect critical fits. Mark press-fit or bearing features on the drawing and agree coating type, target thickness, masking and final inspection dimensions before production.
서로 다른 소재와 마감 처리에서 특정 색상을 일관되게 맞출 수 있나요?
Color matching across materials is challenging but achievable within defined tolerances. Anodized aluminum, painted plastic, and powder-coated steel will never be identical under every light source due to different surface physics. Approve a master color sample and agree the viewing light, measurement method, tolerance and batch acceptance plan before production.
부품의 표면 마감 처리에 대한 조언이 필요하신가요?
Send a drawing or reference photo, material, quantity, finish target, critical dimensions, service environment and any required tests. We will review feasible options, sample approval and the project-specific quotation before committing to a process.
