Antenna Housing Mold Components, Machined to Your Drawing

Forming Components

Core and cavity components create the housing’s external surfaces, internal volume, ribs, and bosses. Custom inserts localize wear-prone or revision-sensitive details without replacing a complete block.

• Specify shutoff geometry and primary datums.
• Identify cosmetic and RF-adjacent surfaces.
• Separate replaceable inserts from base blocks.

Motion And Ejection

Slides and lifters form undercuts that cannot release along the main opening direction. Ejector pins, sleeves, blades, and return elements must distribute release force without marking visible surfaces or distorting thin sections.

• Match slide travel to undercut clearance.
• Locate ejectors away from cosmetic faces.
• Define pin, sleeve, or blade contact areas.

Guidance And Thermal Control

Guide pins, bushes, interlocks, and locating elements protect alignment at parting and critical insert interfaces. Cooling-related inserts support repeatable cycle behavior where local heat removal needs controlled geometry.

• Standardize catalog guidance where suitable.
• Draw custom interlocks and cooling inserts.
• Call out sealing and service access.

Core And Cavity Steels

P20-type pre-hardened steel suits many moderate-volume cores and cavities with practical machining and repairability.

H13-type through-hardened steel better supports wear resistance and polish retention when production demand and abrasive resin justify heat treatment.

Corrosion And Thermal Choices

High-conductivity copper alloys can improve local cooling, but require controlled placement, support, and maintenance planning.

RF And Resin Review

Glass-filled resins increase wear at gates, slides, and shutoffs; hardened inserts may be more economical than hardening every component.

RF performance depends on molded-resin grade, wall consistency, fillers, coatings, and nearby metal. Confirm these inputs before locking steel.

Parting And Shutoff Strategy

Parting lines should avoid visible show surfaces and antenna-adjacent walls where flash or mismatch can alter assembly gaps. Draft, shutoff angle, tool access, and allowable witness lines need approval on the 3D model.

Structural And Cosmetic Features

Ribs, bosses, inserts, texture, polish, logos, gates, vents, and ejector locations require coordinated datum references. Specify whether markings are raised, recessed, laser-applied, or excluded from polished zones.

RF And Validation Inputs

RF regions require consistent nominal walls and an early review of nearby metal inserts, conductive paint, plating, or shielding. Supply the 2D drawing, 3D model, CTQ tolerances, material specification, mating parts, appearance standard, samples, and validation plan.

Datums And Fit Control

Three datum references should govern coordinate callouts, gauge setup, and replacement-part interchangeability. Define CTQ tolerances, mating clearances, and allowable alignment variation before steel is released.

• Identify primary, secondary, and tertiary datums.
• Specify shutoff contact and flash acceptance.
• Record component IDs and drawing revisions.

Surface And Edge Integrity

One approved finish sample should define texture direction, polish level, gate-adjacent appearance, and permissible EDM witness marks. Specify edge breaks where sharp edges could gall, chip, or mark the molded surface.

• Set visible-surface defect limits.
• Define burr and sharp-edge acceptance.
• Confirm shutoff damage criteria.

Thermal Stability And Traceability

Each specified heat-treatment condition requires material identification, sequence control, and verification appropriate to the order. Confirm cooling-path cleanliness, leak checks, inspection method, report format, and replacement-component acceptance criteria.

• Tie measurements to datums and revision.
• Define cooling-test conditions.
• Separate wear limits from cosmetic limits.

Engineering Review

Before quotation, ask which datums, critical dimensions, tool-access limits, electrode strategy, wire paths, and grinding allowances require clarification. Request a marked drawing or DFM log with revision identifiers and ownership for each action.

One engineering contact should confirm material, heat treatment, surface requirements, quantity, application context, and target date. Ask how drawing changes are acknowledged before machining begins.

Evidence Before Order

Three evidence sets matter: material traceability, first-piece inspection, and final documentation. Request sample report formats, instrument identification, measurement-method selection, and the link between reported dimensions and drawing revisions.

One nonconformance workflow should define containment, root-cause response, disposition approval, rework verification, and corrective-action timing. Ask whether prototype and low-volume orders use the same revision-control discipline.

Project Control And Confidentiality

One project plan should show milestones from drawing review through machining, EDM, grinding, fitting, inspection, and shipment. Confirm the reporting cadence, escalation contact, packaging requirements, and how delivery changes are communicated.

One confidentiality discussion should establish permitted file access, retention, return or destruction expectations, and NDA requirements. Do not assume a certification, capacity, tolerance, or lead-time claim without current project evidence.

Late RF Decisions

One late RF change to resin, wall thickness, coating, or nearby metal can invalidate tuned performance after tool construction. Freeze the antenna keep-out geometry and evaluate representative materials and finishes before release.

Two teams—RF and tooling—should review gates, ribs, bosses, and joining features together. Record approved alternatives through revision control rather than relying on informal assumptions.

Incomplete Moldability Definition

Three drawing gaps cause recurring rework: incomplete tolerance stacks, insufficient draft, and vague texture callouts. The result can be binding ejection, cosmetic variation, or dimensions that cannot be inspected from stated datums.

Four items require explicit agreement: datum scheme, draft by surface, texture grade and direction, and permitted variation. Identify gate vestige and ejector-mark locations as controlled cosmetic areas before electrode and steel decisions.

Weak Supplier Controls

One unclear inspection plan creates disputes when parts meet a general drawing interpretation but fail functional assembly. Define critical dimensions, sampling or reporting expectations, measurement method, and revision-specific acceptance criteria in the RFQ.

Two quotations with different process routes are not directly comparable. Evaluate quoted price alongside material traceability, heat-treatment sequence where applicable, inspection evidence, change control, and delivery risk.

Freeze The Input Package

Gate 1 requires released 2D drawings, available 3D models, resin and heat-treatment requirements, quantity, and target date. Engineering approves DFM actions covering draft, tool access, gate location, electrodes, wire paths, and grinding stock.

Gate 2 releases controlled component drawings and a quotation scope. Procurement confirms commercial terms only after technical assumptions and exclusions are visible.

Prove Tool And Samples

Gate 3 approves material evidence and the inspection plan before machining. SUUXIANG supplies first-article results against identified CTQs; the buyer disposition is accept, conditional accept, or corrective action.

Gate 4 follows tool trials with molded samples validated for fit, appearance, sealing, and RF performance by the responsible customer teams. Production release requires signed sample disposition and closed deviations.

Control Engineering Changes

One change notice carries the part number, revision, reason, affected dimensions, effective date, and approver. No email-only instruction should supersede the controlled drawing.

Each change triggers impact review for tooling, electrodes, inspection, samples, cost, and delivery. SUUXIANG should acknowledge the revision received and retain matching manufacturing and inspection records.
