Typical requirements of electronic customers (consumer electronics, connectors, smart wearables, automotive electronics, etc.) for mold suppliers
| Challenge | Description | Two-Wing Answer |
|---|---|---|
| Tiny parts with strict tolerances | Connector terminal hole spacing is ±0.01mm, with a wall thickness of less than 0.3mm | Micron-level processing capability, CMM full-size report |
| Product iteration is fast, and delivery deadlines are tight | From drawings to T0 samples, it requires 3-4 weeks | Standard mold base + rapid insert, concurrent engineering shortens the cycle |
| Thin-walled parts are prone to warping and deformation | High material fluidity is required, and cooling needs to be precise | Mold flow analysis optimizes filling + 3D conformal cooling |
| High surface quality | High gloss black, transparent parts, glass-like effect | Mirror polishing (SPI A1) to avoid appearance defects |
| Mass production stability | With production volumes often reaching millions of units per month, the CPK needs to be ≥1.33 | The process is controlled, and key dimensions are monitored using SPC |
| Insert injection molding | Embedding metal nuts and PIN needles | Automated/semi-automated insertion of inserts to ensure positional accuracy |
✅ We do not exaggerate our ability to achieve a wall thickness of 0.1mm or a precision of 0.001mm, but we are highly proficient in the range of 0.3~1.5mm wall thickness and ±0.01~0.02mm tolerance, which can meet the needs of most electronic components.
Solve common problems for users
| Electronics field | Typical parts | Common materials | Mold technology key | Conventional capabilities |
|---|---|---|---|---|
| Consumer electronics | Mobile phone mid-frame, card tray, buttons | PC/ABS, PC, PMMA | Thickness: thin-walled (0.6~1.0mm), high appearance quality | Tolerance: ±0.02mm, high gloss/fine sparkle pattern |
| Connector | TYPE-C body, USB shell, card holder | LCP, PA9T, PBT | Precise positioning, multiple terminal holes, flatness control | Hole positional accuracy ±0.01mm, high-temperature material molding |
| Smart wearable devices | Watch case, earphone charging case hinge | PC, PC+GF, TPU | Micro precision, dual-color/rubberized | Mold tonnage: ≤200T, part weight: ≤5g |
| Sensor/Module | Sensor housing, camera bracket | LCP, PPA, PPS | High heat resistance, low warpage, insert molding | Insert automatic embedding, with a dimensional CPK of ≥1.33 |
| Power Supply/Adapter | USB Housing, Plug Inner Mould | PC, PA, PBT | Flame Retardant V0, Thin Wall | No Shrinkage Mark on the Surface, Meets Safety Creepage Distance Requirements |
| Automotive electronics | Vehicle connectors, controller housings | PA66+GF, PBT+GF | High temperature resistance: 125℃+, vibration durability | PPAP level 3 in cooperation with automotive customers |
Note: We do not produce PCBs or integrated circuits; we only provide molds and mass production of structural plastic parts through injection molding.
Technology is the accumulation of experience from continuous production and sales
To run a business means to keep one's word and deliver what one promises
| Project | Our Approach and Commitment |
|---|---|
| Mold FAI: | Provide a CMM full-size report (including positional and profile accuracy) for each new mold |
| Process capability | Key dimension CPK≥1.33, SPC control chart available |
| Mass production stability | Each batch includes a first article inspection, a 2-hour patrol inspection, and a final article inspection, with records kept |
| Material traceability | Provide material certification (COA) and RoHS/REACH compliance declaration |
| Mold life | Connector mold ≥ 1,000,000 mold cycles, ordinary structural parts ≥ 500,000 mold cycles |
| Exception Handling | Respond to customer complaints within 24 hours, provide an 8D report and evidence of improvement |
This is closely related to our advantages
| Advantages | Specific description |
|---|---|
| Precision mold experience | We have delivered over 100 sets of electronic molds, covering connectors, wearables, consumer electronics, and more |
| Price competitiveness | Small and medium-sized enterprises have low management costs, and their mold prices are 15~25% cheaper than those of larger factories |
| Response speed | DFM report ≤ 2 days, T0 trial mold (simple mold) fastest 12 days, mold modification ≤ 3 days |
| One-stop service | mold + injection molding + post-processing (laser marking, silk screening, simple assembly) |
| Visual project management | Weekly progress photos + videos, allowing customers to confirm remotely |
| Welcome to factory inspection | Feel free to visit and inspect our CMM, CNC, injection molding machines, and measurement room at any time |
A case is an important indicator to prove whether a company can cooperate or not
Our primary objective is to solve different problems for each customer
| Problem | Reason | A solution with two-wing |
|---|---|---|
| Incomplete filling of thin-walled parts | Insufficient filling pressure/speed | Optimize the gate position/quantity, increase the runner, and select high-flow materials |
| Pulling hair on connector terminal holes | Insufficient demolding slope or mold wear | Increase demolding angle, cavity polishing, titanium plating treatment |
| Transparent parts with bubbles/silver patterns | The material is not dry or trapped in air | Forced drying (dew point -40 ℃), adding exhaust ducts |
| Adhesive overflow of embedded parts | Collapse during mold closure | Optimize the positioning of the embedded parts, reduce the clamping force or increase the overflow groove |
| Size batch fluctuation | Stability of injection molding machine or narrow process window | Lock the recommended machine, optimize the DOE process, and tighten the internal control line |
| Short lifespan of molds | Material wear or insufficient design strength | Wear resistant steel (SKD11/SSAB88) is used for key parts, with wear-resistant blocks added |
