Electronics & Electrical Components
Precision is critical when molding around metal terminals, pins, and connectors. Vertical clamping holds inserts in place by gravity during mold closing - essential for multi-pin connectors where each pin must stay in its cavity.
DA and DC Series vertical machines can be reviewed for electronics and electrical component projects. Rotary table or tie-bar-less configurations depend on insert type, loading method, and production volume.
Application Overview
Electronics and electrical component molding with vertical machines
The process
An operator places metal terminals, pins, or connector inserts into the lower mold. The vertical clamp closes from above, holding them in place. Engineering plastic is injected around the contacts, and after cooling the insulated, assembly-ready component is ejected.
This produces electrical components with precise contact positioning - no secondary assembly, no terminal staking.
Why vertical clamping matters for electronics
Multi-pin connectors and terminal blocks require each metal contact to stay in its exact cavity. In a horizontal machine, pins can shift under their own weight. Vertical clamping provides natural retention via gravity. This matters for:
- Multi-pin connectors where each pin must stay in its cavity
- Terminal blocks with metal contacts requiring perpendicular positioning
- Surface-mount connectors needing precise coplanarity
- Applications where operators manually load delicate terminals
Common Challenges
Production challenges in electronics molding
Insert positioning, material performance, and production efficiency determine connector quality and electrical reliability.
Terminal and pin positioning
A shifted terminal means a scrapped connector or intermittent electrical contact. Vertical clamping uses gravity for natural retention. Rotary tables let operators confirm pin placement at a dedicated loading station before the mold closes.
Insert loading access for complex connectors
Multi-pin connectors with dozens of terminals need open, accessible mold area for quick, accurate loading. DC Series tie-bar-less design removes front tie-bars for unobstructed access.
Material performance for electrical applications
Electrical components require specific dielectric strength, heat resistance (for reflow soldering), and dimensional stability. Materials like PBT, PPS, and LCP need precise temperature control and consistent process parameters for repeatable electrical part quality.
Configuration Review
Recommended machine configuration for electronics components
Starting points - final selection depends on connector type, pin count, material, mold design, and production volume.
Machine series
DA Series
Standard vertical clamping + vertical injection. Broad coverage - small connectors to electrical housings. Fixed, slide, or rotary table. 15T-800T.

Machine series
DC Series
Tie-bar-less vertical clamping. No front tie-bars - open access for manual terminal and pin loading. 45T-120T.

Table configuration
Rotary table
Multi-station rotating table. Load terminals at one station, mold at another - operator time overlaps cycle time. Suits connector and terminal production.
View Rotary Table Machines → Table configuration
Tie-bar-less
Open working area without front tie-bars. Preferred for manual loading of multi-pin connectors and delicate terminal placement.
View Tie-bar-less Machines →Machine size must be confirmed from project data - Review projected mold area, cavity count, pin count, material, and mold design before selecting tonnage.
Materials
Typical materials for electronics molding
Material selection depends on electrical requirements (dielectric strength, arc resistance), thermal requirements (reflow soldering temperature), and mechanical requirements.
PBT
Electrical connectors, good dimensional stability, low moisture absorption. Common for terminal blocks and PCB headers with molded-in metal contacts.
PA66 (Nylon)
Mechanical electrical components, good strength, glass-fiber grades for higher stiffness. Used in relay bases, switch housings, and structural electrical parts.
PPS
Often reviewed for high-temperature electronics, automotive under-hood connectors, and surface-mount electronic components. Chemical resistance and reflow suitability should be confirmed from the material grade data.
LCP (Liquid Crystal Polymer)
Ultra-high-temperature SMT connectors, very low warpage. Used in fine-pitch connectors and applications requiring extreme dimensional stability.
PP (Polypropylene)
General-purpose electrical parts, good electrical insulation, cost-effective. Common in appliance electrical housings and consumer electrical components.
Thermoset / BMC
Electrical insulation components, switchgear parts, high arc resistance. Traditional materials for circuit breakers, terminal blocks, and electrical distribution parts.
