BOSS DESIGN SPECIFICATION HOLE PREPARATION

Moulded Holes are recommended wherever possible. The taper on a moulded hole should bi I。

Inclusive and the hole diameter

recommended should apple at the point reached by the bottom of the insert. Drilled holes may be used but performance may be reduced when compared with a moulded hole. The top of the hole should not be chamfered or counterbored and care must be taken to avoid bell mouthing. Hole diameter tolerance:-0.00+0.10mm

WALL THICKNESS

A general guide to minimum wall thickness is given in the data table but this will vary depending upon the nature of the plastic. Where thinner wall are required these can often be accommodated, but consultation with the Technology Centre of Local Sales Office and pre-production testing is strongly advised.

INSTALLATION

The fastener may be installed using either a pre-heating process of

Using heat generated by ultrasonic vibrations. Where preheating is used, care must be exercised to ensure that the fastener softens but does not melt the plastic. This will avoid any tendency to generate unsightly flash around the top of the insert. Ultrasonic installation is best carried out using low amplitude vibration and the minimum power consistent with satisfactory softening of the plastic material.

In either case excessive pressure should be avoided, since this may result in the insert being forced into the hole without allowing the plastic to soften and flow around the surface profile.

PERFORMANCE DATA

The complexity of materials and variations in service conditions make It impossible to detail fastener performance for specific applications. The chart below gives a general guide and show the relative performance of the inserts in the range.

STUDS(IMPERIAL)

塑胶孔径之设计 1. 各规格螺母之塑胶建议孔径，请参考规格表。 2. 塑胶孔径内之脱模斜度应于1度以内。

3. 塑胶内孔径之公差应设计在-0.00+0.10mm的范围。 4. 塑胶孔上方可以不设计导角。

塑胶孔肉厚 1. 建议肉厚，请参考规格表。

2.

肉厚可视不同塑胶材质，而略作调整，但请先与相关技术人员联系，必要时我们将协助测试及作最适当之建议。 装置 1. 可使用热熔; 超音波或射出成型中埋入。

2. 热熔温度不可超过塑胶材质之熔点，应低于熔点10-20度。3.

使用热熔及超音波埋入螺母时，所设定之压力、时间、速度，需视所使用之螺母规格及塑胶材料种类来调理想值。 4.

射出成型中埋入时，请特别注意模具上所使用套筒尺寸，须配合螺母之内孔径公差范围，切勿大于公差之下限值，请于开模前咨询相关技术人员，以取得建议值。

BOSS DESIGN SPECIFICATION HOLE PREPARATION

Moulded holes are recommended wherever possible. The taper on a moulded hole should be 0.5。

inclusive and the hole diameter recommended should apply at the point reached by hole bottom of the insert. The of the hole should not be chamfered or counterbored and care must be taken to avoid bell mouthing. Hole diameter tolerance: -0.00 +0.05mm.

INSTALLATION

The fastener has been designed for installation using a pre-heating process. Care must be exercised to ensure that the fastener softens but does not melt the plastic. This will avoid any tendency to generate be avoided, since this may result in the insert being forced onto the hole without allowing the plastic to soften and flow around the surface profile.
